Hi John, great question 🙂
This is however in the realms of custom WooCommerce development. So, while I appreciate you are doing this in the context of selling tickets to events, it’s really something where you would need to dive into the WooCommerce API (and or work with the Woo team or someone who is suitably knowledgeable with regards to that product) to figure it out. A ticket is, ultimately, nothing more than a regular shipped WooCommerce product.
We can leave this open to see if other members of the community have a solution they can share – it isn’t something that we can really help you with though, I’m afraid.
