Hi @danflourish

It appears that you may be able to achieve this using the following free plugin developed by a third party:

https://www.wpdesk.net/docs/flexible-checkout-fields-pro-woocommerce-docs/

In case you need custom development help, to build this, we highly recommend contacting one of the services on our Customizations page (https://woocommerce.com/customizations/).

Thanks!
