Handling cards I don't own

It would be really nice if it was possible to get a list of cards that I don't own in a deck. Additionally it would be useful if I could directly move those into my wishlist, or add them to my shopping cart on tcgplayer.com via their mass product entry feature.

I almost have this feeling that this feature should already be hidden in here somewhere, since deckbox is already calculating the value of all the cards that I don't own.
