remove an official from a game once they decline
When an official declines a game assignment their name would be removed from that game and the game time would be blocked on their calendar. The system would flag the assignor of the need to reschedule the game.

We’re not in favor of automatically blocking availability, however, we have incorporated a new feature today which will prompt officials immediately to close their availability for a day when they decline an assignment. To use the new feature, you’ll need to ensure the Availability Locking system (Feature #3) is set to either “Only if unaccepted” or “Never” in order to permit officials to immediately change their calendar when they decline an assignment. Thanks for submitting an idea.
