Use as On-Site Favorite/Shortlist Plugin?

Sorry to bother you guys. I run a small live bands booking agency website.. I’m having real trouble trying to find a simple bookmarking (or favortes) plugin, that will allow my customers to view a band page, then shortlist, or favorite, any of the bands they like, so they can then send me the finished shortlist, so I can see if the bands are available for their event date. Is there a way I could use this for that?

Thanks, Stu.
