I don't think so. Cip just decided that they won't stack.One weird example is when you have one item (rings, shields, etc) at the action button it'll appear the number of itens you have even though they are not stackable, but each of them have their own properties (time, imbuements, etc). Itens such as Surprise Bags don't have properties, just a condition that say it is usable (like foods)
