I'm about to start digging out a flashy tomb for my fort's baron, and I want to engrave it wall-to-wall. I'd like to let only my best engraver do the work. I could lock him in easily enough, but I don't want to risk him starving if I forget about him and he runs out of food. Is there some way to keep the other engravers out while still allowing the good one to leave when he needs to?
Edit: screenshot attached.
Further plans involve a gold sarcophagus, gold and silver statues, and maybe some stupid magma tricks.

The tomb has been completed, and here's the payoff:
