This is one of the key pieces of feedback from our Group clients. They would much rather a summary of tickets rather than each ticket listed on it's own line.

Yes please. Even the ability for the show name and date to not be a loop tag so that the performance name, time and date can be used once and ticket numbers can be listed in a single line each would save a lot of space in group bookings in particular. I've done a mock-up if it's helpful or anyone agrees with it?
