I have a wishlist module I purchased for customers to create wishlists and add products to it and such. I would like my customers to be able to add products to their list directly from the category pages displayed using product-list.tpl.

However, the module identifies the products by the id_combination id which is not defined for individual products in product-list.tpl . So I was wondering is anyone knew or could come up with a way to create the correct id_combination for each product listed by product-list.tpl.
