Feature Suggestion : Show Price excluding Collection

{"ops":[{"insert":"Hi!\nI've recently been building a lot of decks, and inserting my collection into the Program, but what I always found while building Decks, was that, to actually see the Price of the cards I need to buy, I had to throw everything I owned into the Maybe Board to have it be excluded from the shown price. It'd be neat if you could just over over the price, and below showing you how much it costs without Basic Lands, have it also show you how much it costs, excluding cards you own. \nIndependant of Rarity/Version too ofc. \nWould really make price managing a lot easier, especially when you're like me, who sorts everything neatly by Ramp, Draw, Tutor, etc. \n\nThanks for your time! :D\n"}]}
