This will help sites with active PIT/Forklift activity in the Locus zone to keep robots and forklifts separated. They could highlight an aisle or area to clear robots, temporarily eStop them, and/or create a temporary "no go" zone. Client Fleet Monitor functionality?
Although slightly less ideal, allowing Congestion Manager to be set to 0 (which I don't believe is currently possible) would greatly help with this. The client has control over CM limits already. With CM set to 0, the only traffic would be "through" traffic - so if the client sets up temporary barriers at aisle ends (as many already do), those bots would reroute about the same as if there was a true temporary NoGo.
