Modify featured products feed

[Shop Suey]

Is it possible to show featured products which are filtered by category, manufacturer or name?
At the moment I'm using this code snippet:

<?php require($template->get_template_dir('tpl_modules_featured_products.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_featured_products.php'); ?>

which seems to load:

require($template->get_template_dir('tpl_columnar_display.php',DIR_WS_TEMPLATE, $current_page_base,'common'). '/tpl_columnar_display.php');
