It would be great to have an option for complete sets that is analogous to the "Built Decks" option. I would like to be able to mark each set with a number so that I can show how many of that set I have (or would like to have) completed. My crude work-around is to make each set a separate deck, include them within a folder named 'Sets' that I can keep unexpanded, and then mark each set as a built deck.
