Hey Nick,
Thanks for clarifying! 🙂 I am familiar with this extension, I think I just misunderstood you at first!
So, this extension is designed to add the information to the order confirmation (after check out). If you’d like to add this info to the check out screen as well, you’ll want to customize that template, which isn’t something we can do on these forums (they’re reserved for troubleshooting conflicts and bugs with the out of the box features our plugins offer).
If you need to create this functionality, I would suggest checking out WooCommerce’s theming docs and our Themer’s Guide. 🙂 You could also reach out to a freelancer, we have a list of some here.
Let me know if you have any further questions about this or if I’ve misunderstood anything!
Cheers,
Shelby 🙂
