Starting with SC 3.6 we added this ability. By default if agent is configured we send to agent if agent isnt configured we send to server. In addition you can use following tags for more granularity AGENT, SERVER, CLONETARGET.
Here would be example of running you command on server:
Make sure there is a space between SERVER: and then command
In addition the CLONETTARGET is second agent you can have so allowing commands to go there provides two agents and a server from same config which give you a lot of potential. In SC 4.0 (it is in development) we are taking this a step further so any CMD you can send to any agent by just specify agent.
It is the next release after 3.6 so target is beginning of 2013, however that is fully supported release from NOW. As with every SC release we do an open source community supoorted release and that we hope to have out in next few months. I wouldn't quite recommend community release in production envs unless you / customer are comfortable with a community based support model and do fair amount of testing but it is great for seeing new features, testing them, and getting us feedback in time so we can make adjustements before the NOW release
