Hi there @liammcluckie ??
Thank you for contacting Woo support!
I am wondering if it’s possible to add additional data to the WooCommerce orders report export.
Adding columns to analytics reports are a fascinating way to add functionality to WooCommerce.
My recommendation would be to check out this guide:
https://developer.woocommerce.com/2021/02/04/adding-columns-to-analytics-reports-and-csv-downloads/
The resource at https://developer.woocommerce.com is invaluable for such inquiries, and has a handy search functionality up-top.
I trust that points you in the right direction, cheers!
