Attach sets of data to leads

Attach sets of data to leads

On my website users are allowed to save property search queries which include many search criteria. Think price, location, features and more. Users can save as many search queries as they want. I'd like these search queries to show up in the leads module where I can see and edit those search queries.

Does the leads module support attaching (and editing) any number of sets of the same data? Is there another way I can link leads to such sets of data?
