Hi Marcus,
Thanks for reaching out to us but I’m very sorry to say that we currently don’t allow this kind of behavior inside of our tickets system.
You can try to solve this issue with other WooCommerce plugins and variable products, but I don’t have a full solution to point to you.
I can safely say that this is something that we are currently working on, so In the near future you will see that feature.
Sorry about that again, My Best Regards.
