Filter by Wishlist

I really am in need for the ability to sort out my cards by those that are on others' wishlists. I have thousands of cards for sell on this site, and to consistently monitor the fluxuation of prices for each individual card is almost impossible. I try to focus on the cards that are on wishlists, but I have to go into the cards individually. It is also difficult because you never know that a buyer has the 1988 Topps Dan Quisenberry on his wishlist, but not the 1989 Topps. Or you never know when someone wants the 1987 Topps Steve Boros. It would be extremely helpful (and profitable I would imagine) if we could filter out the cards that are on wishlists.
