Are you saying you can just disengage the half nut, hand crank the carriage back, and restart on the same number?

The only difference between metric and imperial on using threading dial is that with metric you have to start ON THE SAME mark, every time.?

I had that idea a while ago as I had some parts to make that would have been easier to leave in the chuck and go back and forth to the lathe and mill. I considered using carbide tooling to thread a commercial hex block as there was sufficient wall thickness for the threads. I never got around to it but it is still in the back of my mind. If I had a surface grinder making one would be much easier. I have a 10k and have used the printed gears from Ebay with great success making metric threads. I believe I saw a way to use the threading dial on you tube but never tried it. Something about using the same mark on the dial I believe but don't hold me to it.
