can I create a Wide IP as a "slave" to another Wide IP? (flip between pools when the master Wide IP flips)

Two sites in different geo locations. One GTM deployed at each site. One pool per site. There's a Wide IP currently, which is flipped between one site and the other, based on the availability of each pool.

 

I've created another pool on each site, and I need to create a new Wide IP pointing at these new pools. But - I want this new Wide IP to flip between sites based on the status of the old Wide IP. If the old Wide IP points at site A, then the new Wide IP should do the same, regardless of the status of its own pools.

 

Is that doable somehow?
