Integration Ticket limit per user

Hello,

we are a small theater association and want to sell our tickets with this plug in. We want to limit the tickets per user to 10 ticket. In this plug in you can only select between one per user and unlimited.
It would be great, when you could select a limit.

Additionally at the end of the reservation there is a notice: You can get your tickets at the box office.
In our case, the guests will get the tickets in advance at our company party. A personalized text would be great! ??
