AP Import Template - Add Override Location fields

If a vendor invoice is entered manually, there is a check box "Override Dept Loc" and a field to enter in the new location. This forces the invoices to post to the specific GL location, even if the PO is for a different inventory location, which then posts to a corresponding GL location. We would like these 2 fields added to the AP import template so we can continue to import AP invoices instead of manually posting.
