Hi Andy!
Thanks for reaching out to us! 🙂
If you are trying to make a reservation list for when all the tickets have been sold, there is no built in solution to accomplish this.
You could make a few tests adding a new ticket for that purpose (which may be free) and letting people make a reservation through there once the main ticket is out of stock. Then, if someone happens to cancel their tickets, you could edit those orders for the reservation ticket and add a main ticket to it so you can then charge for it.
Of course this is something you need to make several tests on and see if it’s applicable to your case. Is this what you were looking for?
I hope that helps and let me know if you have any other questions.
Best!
Victor
