Hi Lorenzo,
I’m sorry to disappoint, but at this time what you’re describing is currently not possible with our ticketing add-ons.
This is a feature we’ve gotten many, many requests for, and the good news is that we are actively working hard on doing this – it’s a little trickier to implement than you might expect, across all our ticketing add-ons accurately and to ensure that user can use either type of ticket stock, but hopefully this will make it into an upcoming release.
It is not a feature of the next release, and not currently supported. Sorry to disappoint Roby.
Please let us know if you have any other questions or concerns!
George
