Custom pages can be created based on the venue by duplicating the existing default page. The word Default in the page name is then replaced with the map number. The map number is located in the Map # column under Setup >> Venue Maps in Theatre Manager.
There are three TMticketSection_MapDefault pages that look very similar. The page ending in a C is for courses. The page ending in a F is for festival seating or general admission performances. The page without an additional letter is for reserved seating performances. A custom page can be created for these three types of ticket sale and made specific to the venue.
