I think in this case you can just use the sync options to import the WooCommerce fields into UserPro and then use the WooCommerce Billing first name and Billing last name fields in your registration page setup. Just change the label and placeholder and the right first and last name will be shown on both sides.
My similar problem is getting hugh here now because not only do i need to use the basic WooCommerce fields for the name but i also need to add fields to the user profiles like date of birth and gender. Those details need to be shown on the WooCommerce orders also but i can’t seem to find an option of solution for that anywhere …
