Hi Paul,
Thanks for reaching out!
There is not a way to do this out of the box, but you might be able to get this set up with some third-party WooCommerce extensions which allow you to bundle products like this. Since tickets are essentially WooCommerce simple products, they typically work pretty well with extensions like this, but you would need to test it out to make sure that you could get it working the way you need.
Alternatively, you could do a customization. If you’d like to give this a shot, our themer’s guide is the place to start! We also have a list of recommended developers that you could contact if you’d like to have the code done for you.
If this is a feature that you would like to see added in the future, please do let us know over in our Feature Ideas Forum! This is what we use to gauge user interest in new features and help guide future development efforts.
I’m sorry I don’t have a better answer for you at the moment, but please let me know if you have any questions!
Thanks,
Jennifer
