bpduplicate script for specific policies

Hi everybody

I have in my Netbackup environment daily and weekly duplications. The daily duplications are ran manually but the weekly duplications run by bpduplicate scripts. Follow my actual script:

bpduplicate -dstunit 6drivesLTO4Prod -dp Datasafe -rl -1 -fail_on_error 0 -set_primary 0 -primary -number_copies 1 -mpx -L "D:\VERITAS\NetBackup\Logs\NBduplicate\Dup-FDS-1_mpx.log" -hoursago 36 -M bnpbkp1

Now i need to change my script to select specific policies that will be duplicated. I checked all the parameters to be used with bpduplicate and found the parameter -policy. It worked perfectly with ONE policy but i need to run for 20 policies. I can make one script per policy but its crucial that all duplicatation run inside only ONE job.

There is a way to do that?

Best Regards and Tks.! :)
