Is it possible to override rpt.index and rpt.qty in repeat region table?

Greetings:

I have a repeat region table with bulk items similar to this

---------------- CURRENTLY ---------------------------------- Item Description P/N QTY

--------------------------------------------------------------

1 Primer, Zinc Yellow MIL-P-2-1 AR 2 Primer, Zinc Green MIL-P-2-2 AR

and would like to make item #2 and QTY in the second row as 1 and ALT instead

---------------- DESIRED ----------------------------------- Item Description P/N QTY

--------------------------------------------------------------

1 Primer, Zinc Yellow MIL-P-2-1 AR 1 Primer, Zinc Green MIL-P-2-2 ALT

Is it possible to override the rpt.index and rpt.qty in the 2nd row to an user define value? If not, how would you do this?

Any help would be greatly appreciated.
