Monitoring Agent - Bulk Change

I need the option to do a bulk migration of devices to a different monitoring agent. I don't know why this is automatically chosen instead of being monitored by the original search agent in Network Discovery. It's very non-intuitive. When I go to delete a monitoring agent it says move all monitored agents. I have to click EACH AND EVERY device that is being monitored by this agent. It's painfully time consuming. I would also be better for the selected monitoring agent to be a server rather than some random PC that goes offline or might be removed. Or give me the option of selecting a new agent when I go to delete it and do the bulk move in the background.
