Not exactly.

 

However, you can simulate the effect you are looking for by creating a sync-failover device group with three members, where the traffic group is set to use 'Failover using Preferred Device Order and then Load Aware' and has 'Always Failback to First Device if it is Available' enabled.

 

You then specify your devices in the order site 1 device A, site 1 device B, site 2 device. The site 2 device will only be used when neither site 1 device A or B are available. If the site 2 device is active, and either (or both) site 1 device becomes active, the traffic group will fail back to one of the site 1 devices.
