Switch drive pools between same job automatically??

Is there a way to switch drive pools on the same job automatically?  Sort of rotate between 2 drive pools?  Or do I need to have 2 separate jobs for this?

So if I have drive pool 1 & 2, can the full backup job use drive pool 1 on one week and drive pool 2 on the next, then go back to drive pool 1 on the 3rd week, etc....??
