Paginate results rendered using perch_template or...

I'm displaying a set of search results limited to PerchShop and paginating them. This works great.

I'm now trying to access a custom flag on the category for each product so that i can render a different URL for these search results.

On search.php I have the following which renders the search results and pagination correctly but the call to each does not seem to do anything. Is this implemented/supported. Getting this to work would be the ideal solution.

            perch_content_search(perch_get('q'),[
                'apps' => ['PerchShop'],
                'count' => 10,
                'paginate' => true,
                'page-links' => true,
                'page-link-style' => 'all',
                'each' => function($item) {
                    $cats = perch_categories([
                        'set' => 'products',
                        'skip-template' => true,
                        'filter' => 'catID',
                        'match' => 'eq',
                        'value' => $item['category'][0]
                    ], true);
                    $item['webshop'] = $cats[0]['webshop'];
                    return $item;
                }
            ]);

Secondly I tried the following to get the results and loop through myself getting the category for each. This works but I lose the pagination.

$results = perch_content_search(perch_get('q'),[
    'apps' => ['PerchShop'],
    'count' => 10,
    'paginate' => true,
    'page-links' => true,
    'page-link-style' => 'all',
    'skip-template' => true
],true);
foreach($results as &$result) {
    $cats = perch_categories([
        'set' => 'products',
        'skip-template' => true,
        'filter' => 'catID',
        'match' => 'eq',
        'value' => $result['category'][0]
    ], true);
        $result['webshop'] = $cats[0]['webshop'];
}
perch_template('search/search-result-content.html', $results);

The templates of the above two calls are the same aside from the namespace the first uses search and the other content.

<perch:before>
    <h1 class="lined">Search results for “<perch:search id="search_key" />”</h1>
        <ul>
</perch:before>

        <li class="<perch:search id="perch_item_odd" />">
          <a href="<perch:search id="result_url" replace="/shop|" />">
              <h4><perch:search id="result_title" /> (<perch:search id="webshop" />)</h4>
              <perch:if exists="result_excerpt"><p class="excerpt">…<perch:search id="result_excerpt" encode="false" />…</p></perch:if>
          </a>
        </li>

<perch:after>
    </ul>
    <perch:if exists="paging">
        <ul class="pagination">
            <perch:if exists="not_first_page">
                <li class="prev-page"><a href="<perch:search id="prev_url" type="hidden" encode="false"/>" class="icon-arrow-left"></a></li>
            </perch:if>
            <!--*<li class="active">Page <perch:search id="current_page" type="hidden" /> of <perch:search id="number_of_pages" type="hidden" /></li>*-->
            <perch:search id="page_links" encode="false" />
            <perch:if exists="not_last_page">
                <li class="next-page"><a href="<perch:search id="next_url" type="hidden" encode="false" />" class="icon-arrow-right"></a></li>
            </perch:if>
        </ul>
    </perch:if>
    <perch:showall/>
</perch:after>


<perch:noresults>
    <perch:if exists="search_key">
        <h1>Search results for “<perch:search id="search_key" />”</h1>
    <perch:else />
        <h1>Search</h1>
    </perch:if>
    <perch:if exists="search_key">
        <p>Sorry, there are no results for “<perch:search id="search_key" />”.</p>
    </perch:if>
</perch:noresults>

Is it possible to get either of the above scenarios to work? Have I done something silly to prevent them from working as expected? Finally, Is there an alternative/better way to achieve this?

Thanks
