Content Custom show two filters in results.

Hi there.

I'm using content custom to bring in some content from another page and separate the results based on a filter. However, with some of the results I'd like them to feature on other pages using a different filter i.e have a folio item that appears on both a web design service page and an illustration page (if it features it)

Currently using this to bring in my results, which all works fine.

        <?php $opts = array(
        'template'=>'homepage-work.html',
        'page'=>'/graphic-design-portfolio.php',
        'count'=>4,
        'filter'=>'category',
        'match'=>'eq',
        'value'=>'illustration',
);
perch_content_custom('Folio Work',$opts); 
?>

it's the addition of a second filter that I'm having trouble with, From the content_custom page on the perch I thought I could do the following and add in a second filter using an array. but I'm not getting any results doing the following... anyone have any clues what I'm doing wrong? or even if it's possible

    <?php $opts = array(
        'template'=>'homepage-work.html',
        'page'=>'/graphic-design-portfolio.php',
        'count'=>4,   
        'filter'=> array (
        array(
        'filter'=>'category',
        'match'=>'eq',
        'value'=>'illustration'),

        array(
        'filter'=>'category2',
        'match'=>'eq',
        'value'=>'illustration'
        ),
     ),
);
perch_content_custom('Folio Work',$opts); 
?>

Many thanks in advance
