Support for pushed (or pulled) firewall rules in groups

As the Sophos Firewall Manager (SMF) doesn't yet support deploying firewall rules in groups, is it supported to move the pushed (or pulled) rules into groups on each appliance?

If we put rules in groups, we see they are then removed from the group if they are updated and redeployed.

 

I can't see anywhere stating this is supported / unsupported.

 

We are also investigating abnormal behavior with rules that have been deployed with the SFM (open support case).

Is anyone else having problems?
