Request for 'Demo' option for Wishlist

Some games are getting so old now that they won't work with newer systems, so demo's are a great place to try them out first for us end users. But right now their is no way to search for demo's for the games in the Wishlist. This might also help with too many returns you may have as well due to such things. I hope you can implement this 'Demo' option or tag for games in our Wishlists. Thanks!
