Question on: Scheduling backups to tape library

I recently just sat up PBS, although I'm a long-time VE user. I am attempting to setup a scheduled backup to a tape library for archival purposes. The issue I am running into is that I don't see the option in the drop-down list for the Job's schedule for the particular use case I'm trying to achieve. What I'm wanting to do is.

I have 2 pools of tapes (Library holds 8 tapes at a time, each pool is 8 tapes. Effectively meaning I will need to physically change the media between backups)
I want to schedule a backup so each month I have to swap out the loaded pool with the other. Effectively Backing up on Pool1 on the first day of the month, on months 1,3,5,7,9,11 and pool2 on months 2,4,6,8,10,12. this way I have the previous months backup in the vault.

I know that this would effectively need two jobs (Pool1 and Pool2), but how do I schedule each job for their corresponding months. Cron scheduling doesn't appear to work in this input field.

I think I figured this out:

Pool1 Schedule: *-01,03,05,07,09,11-1 12:00:00
Pool2 Schedule: *-02,04,06,08,10,12-1 12:00:00
