Request option to assign mtg roles to Guests, Prospects, Friends/Affilates

Since membership management currently includes: Guests, Prospects, Friends/Affiliates and Former Members, it seems like it would be useful to be able to assign roles to people in these other categories.  Is there a way of tracking people in these other categories if assigned to a role.  Club Mentors, coaches and mentors might also take roles, but they could be entered into one of the existing categories.
