Hi, Jake.
Event Tickets / Event Tickets Plus is very much setup for single event applications only.
This is why creating an event that has Balcony $10, Mezzanine $25, and Orchestra $50 tickets for a performance on Saturday Night can’t have its tickets re-used… you’d have to create the exact same 3 tickets for a separate Sunday Afternoon event.
I expect such inflexibility will become more flexible to become more administrator-friendly in time as the products continue to be developed.
Some custom code could likely get you what you’re wanting, but it’s not anything built-in.
If you need some coding help, you may want to ask your developer or reference our documentation and list of known customizers.
