After the first one, you probably can import into the same invoice, given the invoice # and line key values... but say you entered a quantity, it would overwrite, not add to the value already in place. Not easy to do.
A better strategy would be to import multiples into a UDT (setting up an appropriate key field), then import the invoices from UDT data (by adding quantities together for each SO & OrderLineKey...).
