Field VAT Number adaptation for Edocument

Hello,

Thank you for your amazing recent work around e-document !

I have a quick question. The UBL generation pulls information from the VAT number, which is required and mandatory for a valid UBL document.
However, the extension retrieves this VAT number from a field called billing_eu_vat_number. Since this field doesn’t exist natively in WooCommerce, I’ve been using (via Checkout Field Editor) the field billing_tva.

Do you have any idea how I could target that field directly within the extension? I could simply rename the field and it would work, but I already have several solutions (including an accounting XLS export) that rely on this field

PS: It only concerns UBL Generation, for classical PDF Template I can use hook without problems.

Regards,

Ludovic
