Maybe a new function to not include certain games?

Sorry if this has been posted before or if there is a better place to post it. I think it would be quicker to sort through the games if you could check off games that you have already (or it can remove them if it sees that it is on your steam account) and that way they would no longer show up then there is no worrying about already having it and bidding on it if your account isn't synced.
