LoadUI Distributed - Unassign mid run

I have been working with LoadUI an few days now and things are going well. I was doing some testing using multiple scenarios on a distributed agent. I found that when I am in the middle of a run and unassign a scenario from a remote agent that the agent stops running all scenarios on that machine untill I put that same scenario back on the agent.

It is really nice to be able to alter what is running on what machine mid run while watching the stats.

Any ideas?

Thanks
