I have photographic prints to sell, and they can be framed as well. I set up grouped variants by size (so for example 24 x 36 - either a matted print, or framed - with two paper types as well, so 4 possibilities for that size).
One issue is that if I set the product cost to say $20 on the product, and set the overridden price (attribute combination) for the framed photo to $100 - I think nop will calculate my profit to be $80, right? Ideally I could set a product cost on each attribute combination.
This probably needs a little thought on the scenarios, but it would be nice.
