Court Lockout OR Option for players booking a reservation to select a different court when someone "beats them" to saving the reservation.

We have many courts and often when players are making bookings in the mornings, they will go to save a court booking and then be told that the court is no longer available and they are forced to go through the entire process of entering the information again for different courts until it gets saved. 

We'd like to either see a court lockout feature, OR the ability for players to get a dropdown of other available courts of the same court type when their booking is declined due to another booking being saved first.
