I'm currently slowly importing my rather large magic collection(>10k cards) into this site. I don't have any card list file currently so i'm entering them by hand. The default values when adding cards to the inventory is nice, but I would really like a default NUMBER of cards. A significant majority of the cards i'm adding are 4x of each card. So my current method is to enter the card, then update the count value to 4, then enter the next card. If I could have an additional field that defaulted 4 (like set, language or quality does now) it would speed up my entry time significantly. It would also be useful when adding decks since most decks contain a lot of 4ofs.

I'd find this feature useful as well, so seconding this request!
