Howdy Jamie,
There is no easy way of currently doing that. Some people have used some WooCommerce additional details at checkout addons to try and fill that gap, with a little bit of success.
That said we are developing that feature and plan to include it soon in a future update to WooCommerce Tickets. If you’re interested we are even going to start testing that feature in a beta program in the next few weeks. I could sign you up!
Cheers!
