Several table assignments can be released simultaneously or assigned automatically.
Open the Table Reservations overview per room or for All rooms.
Select all the reservations you want and click on Release in the horizontal toolbar.
When prompted, decide whether to release only the tables or the room allocations as well.
Select all the tables you want and click Assign in the toolbar to assign a free table with a suitable number of seats to all selected reservations at the same time. If no table has enough seats for a reservation, multiple tables must be assigned manually.
