Improve drag and drop feature on desktop admin panel by allowing us to select 2 reservations and click a button to make them swap places/courts

Select two reservations and click a button that makes them swap places.

Right now, if you want to have 2 reservations swap places, then you have to drag one to an empty court slot to get it out of the way, and then drag the other reservation in its place, then drag the one you moved out of the way to the other reservation's previous place.

I feel like this could be an easy and helpful implementation. I find it necessary because when you drag and drop a reservation, the customer gets a notification that their reservation has changed, and this would minimize the number of notifications they would get while also minimizing confusion when moving that first reservation out of the way to an empty court.
