I don’t already have a template, but you could achieve this a couple of ways. The easiest way that comes to mind would be list all your products in one list and assign them all specific “recommend” categories (x, y, and z would have the same category). Then do a multiple relation to the category. —the only issue with this is that the product they’re currently viewing will also be in the list.
I wish there was a special value filter condition for “is/is not current row”…could also potentially solve this issue I’m having:
Button > Link to Screen > Same List Item?
