Endorse this feature. Relief from micromanagement should not mean inability to manage at all.

Here's another use case: I have a master miner all trained up in an iron mine but the coal miner is less experienced. Both mines are exhausted but I need coal *now*. I'll need iron later -- badly enough to deepen the iron mine -- but for now I just want to deepen the coal mine and reassign the master.
