leave nast-vstat = 0 in sd invoice printing program

we want to run the sd billing document print report, but leave the NAST-VSTAT unchanged (equal to 0) if some conditions are not met for the message (we only want to print the message if an electronic signature was successfully generated for the invoice). The idea is leave the invoce message "yellow" in order to be reprocessed latter by a periodic job, when the problem is solved...

Is there any easy way to do this in the printing report?

Thanks
