For the online store: Filter by "In my wishlist"

I'd love to be able to filter by items that are in my wishlist in the online store.

During the various sales, when I look at the lists of items that some of the categories have hundreds of items - I know that an individual item will have a heart in the upper corner if its in my wishlist, but some of the sales lists have hundreds or even a thousand or more items. It would be nice to be able to quickly see if any of my wishlist items are included in the sale.

It would be convient, and faster, than scrolling through the massive content on the list...

Thanks!
