Creating a Favorites Page

The other option is on either the Members Profile Page, or on the Profile Search Page to Add a Favoirtes Button that has an onClick function, that adds that profile to favorites, and then add a filter in the repeater for “My Favorites”. If I add it in the Profile search Page, do I need to add an additional column in the Content Manager, even though the rest of the content on that page is all created in the Profile Creation Page?
