it is also possible, not easy to do, but possible to program hot keys that automatically paste the deck code for you. other than that the deck code storage idea works just as well if not better. and as zanz pointed out, separate decks takes up lots of memory. what i would like though is more options, like perhaps you could highlight all the cards you wanted to sell/remove instead of having to click over and over and over and over and over and over and over and again.
