Feature Request: Track "Cards I own and have set aside for this deck"

{"ops":[{"insert":"Apologies if this is the wrong place or if this is a duplicate. I just had the thought that I should post this and at least see what happens.\n\nI used to use the collection management feature to mark cards I already had for a deck before moving to tcgplayer to purchase the cards. But I would end up purchasing less cards than I needed. Why? Because I already purchased those cards for other decks using this same method. So duplicate cards between decks were getting missed. I eventually stopped using this feature entirely and found other more manual ways to order my cards.\n\nWhat would get me using this feature again is if there was a way to mark a card in the deck view as \"I own a copy for this deck\". Im sure there's a smoother way to say and implement this. But it would allow me to pull cards from my collection for a single deck, mark those cards as \"owned for the deck\" and then order the rest of the unmarked cards and know FOR SURE that I will get the rest of the cards I need in my shipment.\n\nThanks for reading this!\n"}]}
