Membership Rules that conflict w/in a Reservation

We have VIP memberships which have benefits that other memberships do not have. One is that our VIPs get 4 free guests per month, however our other memberships do not get to bring guests. All of our membership settings are set correctly per the above. However, when a VIP member tries to add a guest to their reservation, and others on that reservation have different membership types, the guests are blocked from being added. This makes it impossible for our VIPs to be able to manage their own free guests and it would be nice to see this rectified

Each membership type has its own set of rules but this is irrelevant if the rules don't apply per membership within a single reservation.  Thank you for your consideration.
