FluidNC - Pause a job / move manually then resume?

I’m running a huge job (flattening an MDF spoilboard) and the carbide cutters on my surfacing bit have gotten dull. (It’s a long story. Didn’t intend to cut as deep as I am. But that’s not the point…)

Is there any way to pause a job in FluidNC so that I can lift the Z axis long enough to change the cutters and then resume? I see that I can pause, but none of the commands I enter on the terminal do anything.

Running the V3 web UI at present.
