perch_content_custom() filter and page?

Hi guys,

I'm trying to pull in pages through perch_content_custom(), but only the ones that match a value specified in a field.

Is that possible?

So far, I have this:

perch_content_custom('Overview', array(
                'page'=>$page['pagePath'],
                'template'=>'work/_item.html',
                'filter'=>'categories',
                'match'=>'contains',
                'value'=>'digital',
            ), true);
