We have a bunch of Sales Orders missing the Billing Address (Bill To Select). How do I mass updated these Billing Addresses on the Sales Orders with the Default Billing Address that lives on the Customer record? When I navigate to the Sales Order, the ability to select the default address used on the customer is available in the list (billaddresslist), but I can't seem to get a csv import to select this option by using the Customer Address Line ID (20503). Any guidance would be appreciated.
