Pause printing until temp setpoint is reached

[zemlin]

3D printing newb here so I might be all wet. That said, I'm dropping the extruder temp a little for the first layer to build on the raft to make the raft a little easier to remove. Then I raise the temp back up for the next layer. On a small build the first layer may complete before the nozzle temp drops to the target temp - and then the second layer is building below temp. Would like to see an option to pause printing until nozzle temp hits the setpoint.

maybe it makes more sense to bump the fan speed for the first layer when I want to cut the adhesion - no response time/inertia issue with that option.
