Unfortunately, we do not currently support varying game durations by division.
You can only set one game duration per schedule.
If possible, we recommend splitting your field times so that only divisions with the same game duration share fields.
You would then either make separate schedules for each of those "groups" of divisions or, if you prefer keeping all divisions on one schedule, set your schedule to the shortest game duration and enter your time slots one-by-one. E.g. if you have some divisions with 60-minute games and some with 90-minute games, enter time slots for the longer division so that each start time has its own time slot (e.g. 9:00, 10:30, 12:00). The shorter divisions can actually be entered as e.g. 9:00-13:00 and the system would recognize that as 4 games (9:00, 10:00, 11:00, 12:00)
