Multi-pass thread

Hello everyone. When cutting multi-input threads, the postprocessor outputs the control program code via G92 and at the same time, threading is performed when the tool is shifted along the Z axis. In the G92 cycle itself, it is possible to specify the Q parameter (in microns value), this parameter allows you to set the starting angle.
Is it possible in the postprocessor to specify this parameter in the G92 cycle or to make a choice when threading to use a Z-axis offset or to change the starting angle.

 

This is how the postprocessor outputs.

That's how I would like it.
