I’m wanting to apply a promotion for items in a certain category, that works fine, but I’d like to reference another field on the product to filter by as well. I can’t find an out of the box solution, nor can I find a contrib module that provides the functionality I need. Is there anything out there that can help, or am I looking at custom?
