For example we manage lockers. And every locker has a number. So when the person responsible for the lockers enters in action he would check a locker that is available (that has no client assigned to it) and then enter the locker record related to the person, assign the locker and then delete the record with the same locker number but with no client. Or assign the empty locker to the client and delete the other record. So my idea to optimize the process would be while editing the form have a multi select field for the locker number so you could easily select the number of that locker record and then have the button gather that information and use it for the edit or deletion.
