If you have Matchi as your booking system, you can also select Cancel in Matchi. This requires that you get a cancellation code from Matchi to the account from which the times are booked in Matchi. If you enter this, the times are automatically canceled in Matchi at the same time as they are removed from the system. In this way, you can book many extra times for the league without having to worry about the times not being used.
NOTE. This option is currently being tested by a number of selected clubs.
