Plasma - post cut delay

I have found with my plasma that I need ~ 10s delay before commencing the next cut, this is the length of time it takes for the airflow to stop following the M5 command on my plasma torch. If I don't delay then the pilot arc does not fire and the next cut is missed (although sometimes it works - hit and miss) I have been adding G4 P10 manually between each cut in the gcode generated by Fusion 360 and 100% success torch fires for every cut. Is there a field I can add a post cut delay in the post processor so it is automatically applied in the code?

 

Hi David - Many thanks for your response, it would be fantastic if you were able to add it to the post settings!
