Pool member status on F5 DNS objects via iControl REST

I got a question on how to retrieve the status of pool members on F5 DNS objects via the iControl REST interface. In the GUI you get fancy red, yellow, black, blue, and green painted circles, diamond...

Is there a way to SET the state of a BIG-IP DNS Pool? In my downstream LTMs, I can intercept error conditions for nodes using an iRule, and if the local Pool has no other members up, I want to signal the BIG-IP DNS that the service is down right away, so I can respond to the client to re-query DNS and pick up another data center. The problem I have is that if I have to wait for all the Health Checks to timeout (both locally on the LTM, and then up on the DNS), the BIG-IP DNS could re-pick the data center with the down service in the meantime, and cause my request to loop.
