Consecutive backup automation?

After many years of backing up to a single drive, I wanted to be able to back up to two drives - one to leave at home, one to take offsite - and this advice worked beautifully except for one thing.

My backups are set to shut down my Mac after completion since I finish working at different times each night and the backup is the last thing I do - manually, due to the varying work times. The good news is that it didn't shut down after the first "scheduled" job, though a system notice about SD preventing shutdown did pop up. The bad news is that it didn't shut down after the second job, either, with another system shutdown notice.

Is it possible to instruct the first job to Do Nothing on completion, but have the second job shut down the Mac? I tried changing the option when setting up the schedules, but changing one changes both.

Thanks.
