It would be helpful to allow multiple subcategories to be selected for a single membership.

For example, we use a Hall of Fame membership, and some constituents are inducted for multiple sports. Currently, this requires creating and managing multiple memberships to reflect each sport-specific subcategory.

Allowing multiple subcategories (Hall of Fame – Football and Hall of Fame – Baseball) to be associated with a single membership record would result in cleaner data and simpler maintenance.
