Is your feature request related to a problem? Please describe.
Customers looking to use the cloud for DR often need to enable / disable advertisement of networks between on-premise and the cloud based on whether they are performing testing or actual failover. E.g. during an actual failover, they may need to advertise cloud networks for full routing and communications capabilities, while during steady-state operations / replication they may need to keep those networks hidden from production on-prem.
Describe the solution you'd like
Prefix filtering to allow / disallow network advertisements has already been enabled for route-based VPN - similar functionality needs to be enabled for DX / SDDC Groups / Transit Connect.
