since SFOS 17 we are able to
- group firewall rules
- move firewall rules aswell as groups to change their position (and therefore the processing order)
- automatically assign firewall rules to the first matching group (if selected)

in central firewall manager none of this is currently possible, i.e. groups are not supported and you cannot change the position of rules

in addition you cannot rename a rule after it has been created

all of this should be possible via central. In the current state rule handling is unusable for our customers.
