F5 sync options

I am looking for some help on F5 sync’ing options. I have opened an F5 support ticket with the below opening notes. However I thought I would reach out to the this forum as well. I wonder if this is even possible?

---F5 opening case notes---

I have some questions about config syncing on the F5s that I would like to discuss. We currently have 2 F5s in an active/standby failover config in our Minneapolis (MSP) location and we also have 2 F5s in the same setup in our Madison (MSN) location. The MSP location is production location and the MSN is our DR location. I would like to take the config that we have on our MSP location and sync it to the MSN F5s. However I don’t want the MSP and the MSN devices to be a failover group. I believe this is possible but I wanted to discuss this with F5 support. We already have the active/standby sync-failover group created in MSP and in MSN so that we have device redundancy in each location. What I believe we need to do now is to add all 4 devices to the trust list and then create a sync-only group and this will allow us to manually sync our config from MSP to MSN.

I have found some links that sort of show this as being possible.

In addition to the above info I have create a diagram of what I am looking to do. It is below.
