Hello Richard,
Thanks for reaching out to us!
There currently isn’t an integrated solution for providing custom information like this within our ticketing plugin. If you like you can add (or “up” vote) this feature request on our UserVoice page for our developers to consider.
Until then, there are some options to add some additional fields on the checkout form to collect this information from your users. There are some plugins available from WooThemes as well as in the WordPress.org repository that may be able help you with integrating this feature.
Let me know if this helps.
Thanks!
