Is there a way to sort the records being processed in Auto Invoice by customer, so that all invoice

Currently the users are filtering Auto Invoice
specifically for each customer, just so that the invoice number range for the
same customer comes in line. As you can imagine if we are invoicing 20 customers,
they run Auto Invoice by customer 20 times.   For example:  if there are 3 lines on the interface table.  2 lines for Customer A for 2 different Orders and 1 Line for Customer B.  So yes, there will be 3 Invoice created and lets say those invoice number which are created are 1001, 1002, 1003.  Is there any way to make sure that when the invoices are created, that Customer A gets either Invoice # 1001 and 1002 or 1002 and 1003.
