Multi Court Event - Auto Drop Courts if number of participants not optimal

When creating an event, you are required to include # of court needed and player amounts. If you have multiple courts selected yet only 4 people sign up (not enough to take up more then 1 court)  there is no option to AUTO drop the extra courts.  (Example: We have open play 2 courts that people sign up for.  It will cancel BOTH courts if I say auto cancel if 4 or less players, instead of just 1) I hope I make sense.
