Multiple schedules change

Good Morning,

Netbackup server 7.5.0.6 running on Windows Platform.

We have over 1500 Schedules in our environment and the Media Multiplexing is set to 8 on all of them.  I would like to up that to 16 on all of them, is there a quick way of doing this instead of doing them 1 by 1?

I know I can use bpplschedrep via the CLI so does anyone have a little script that can be used?

Many Thanks
