Hi. In Export there are specific fields to use for i.e. exporting an Orders csv.
However there are fields that are used in the customer checkout billing form that are not included there.
Why and how can I add them so to be able to export them in a CSV?
Such fields are: Vat number, Tax office, Profession description, subtotal_discount, Options category and Options value (I mean to get the value related to an order, like XXL or size 42, etc), item price (before quantities added)
