Multi region and the failure scenario

Let’s say we have two Nomad regions.
We deploy a job in a one of them.
Is there a way to have this job moved to the other region when the first goes down?

We cannot have single region deployed in a two locations because of network latencies (it is recommended to have less than 10 ms).
So we decided to have two regions. Preferably we would like to have two datacenters each one in a separate region. There is affinity stanza in a job which is great to use one datacenter as a preferable one, but job has also region parameter that requires to have single region specified, so I don’t see how we can setup it to have job moved to the other DC in case of region/DC failure.
