Ideas

Add a new condtion to be able to select products that are in (or are not in) another product list.

For example, say you have a (simple) product list with a lot of "Outlet" products.

Then you would like to have sub lists of this list, for instance lets say you want two other lists with products from the outlet-list thats in category A and another list thats from category b.

Then you could create a smart list with the new condition like this: "products that are in the Outlet-list" AND "products that is in category "A"
