select back from SQL report to SO lines in the order selected

We have a sql report designed to allow the user to enter a qty ordered for each line selected and then write back the selected rows to the sales order lines.

This function fine.  However the customer wants the rows to be written back in the same order as they were selected when selecting rows and entering quantities in the SQL report.

They want the rows to be written back consistent with the behavior when doing multi select from a standard choose from list.

Is this possible?
