Sync ASM security policies between BIG-IPs that are in different datacenters.

In this scenario, the end user has ASM in the primary datacenter, and the application security policies have been configured. This time, they have acquired a new BIG-IP ASM for the secondary datacenter. It will be protectiong the same applications, but located in another datacenters.

What's the best way to synchronize the ASM policies between BIG-IPs that are located in different datacenters? I know I can Export and Import, but is there a way to keep them updated?

I've used Config Sync to synchronize the ASM security policies between BIG-IPs that are located next to each other (HA Pair). Can something similar be used?
