Am I correct in assuming that content which is assigned to a Primary is
not automatically replicated to the Satellite servers associated with
the primary?

I have a Primary server with a few Satellites and the content is not
automatically replicated to the satellite servers. I.e there is not tick
in the Include column on the Satellites.

Currently, I'm manually replicating teh content to Satellites using the
"Specify Content..." menu option.

I've had a look through the Configuration options but can't see anywhere
that will allow content to be replicated to Satellites automatically.

Is this possible?
