This video will demo how to mark/unmark seats as sold.
This feature can be used to block off seats for a particular event, date, etc.
You also have the ability to make your own custom seat map hold labels for marked as sold seats. Custom marked as sold labels can be used to identify blocked-off seats in the box office for particular group categories you set up (like VIP seats).
