Add editable address fields to WooCommerce invoice page

Hi,

I am looking for a way to add editable address fields to the WooCommerce invoice page (form-pay.php), so that when I send someone (usually a guest) an invoice, they can fill in their shipping address. Or in a case of an existing user, where they want to ship to an alternate address.

I couldn’t find a feature nor a plugin that can do this, and I would love to know if it is possible, and if you can lead me in the right direction.

Thanks!
