Be able to pick the completion by "any languages" in the list

It would be nice to have a feature to make lists independent of language, sets or card versions (standard/foil). For example I want to track if I own a playset of every mechanical different card. For example: I want to track if I own four copies of card XYZ which is available in multiple sets and multiple languages. I have one copy in german of set 1 and one copy in english of set 2. It would be nice if those could be merged into a single list entry which says that I am missing two copies.
