S7 and workers and have 2 or more workers

There is a priority setting in Antminer setting's window.
This is usually 0,1,2

Is there a way to make say two setting same priority so you can mine at two pools at the same time.
like 0,0,1

Is there a setting to make it so you can split TH to mine at two places at once?

Sorry about the noob question
Thanks

On the antminer those aren't priority(not adjustable), those are failover pool orders.
As a pool goes offline the next one in order is attempted.
When a higher failover order pool comes back up it switches back.
