Hi Diego,
Thanks for reaching out! I agree, this would be a great feature. Unfortunately we do not currently have an out of the box way to accomplish this, although it could be done with some custom coding. If you’d like to give it a shot, I would recommend taking a look at our themer’s guide, which has some great info on customizing our plugins. We currently do not do customizations like this, but we are always happy to help answer questions and point you in the right direction.
We also have a list of recommended developers if you would like to have someone code this out for you!
If you could cast your vote for this in our Feature Ideas forum, we would really appreciate it! This is what we use to gauge user interest in new features and help guide future development. We have two ideas so far that sound similar to what you are looking for:
Ticket Bundles/Multiple Event Passes
Support Woo Product Variations within Event Tickets Plus
I’m sorry I don’t have a better answer for you, but please let me know if you need any guidance with the code – I am happy to help!
Thanks,
Jennifer
