Support for more than one active membership per user

We would like a user the ability to have more than one active membership at a time, selecting one of them as the primary with the ability to toggle between the memberships.  Which ever membership is currently selected will be the one whose booking rules are enforced.  For example, a user could buy both a tennis and a pickleball membership which has different costs, booking times and booking restrictions.  The memberships could be fee-based or free.
