prevent players from playing in an event and also have a court reservation after the event

It looks like currently the only way to prevent a player from 'double dipping' by playing in an event and then reserving a court right after the event is to have event registrations count towards the reservation limits set by the club. It would be nice if events did not count towards court reservations but the ability to play in an event and then be part of a court reservation either immediately before or after the event be restricted.
