Cancel the reservations of a multiple reservation (Syltek)

The first step is to cancel all unplayed future reservations. To do this:

1.- Go to the Reservations module / Multiple Reservations

2.- In the list of multiple bookings, find the one you want to extend and click on its reference number

3.- Once inside the multiple booking, click on the Cancel next bookings button. This will cancel all bookings from the current date and time until the last future one.
