Linuxcnc postprocessor M67

I don’t use Lightburn often but just recently I started using it a bit more with LinuxCNC and found you have modified the postprocessor to use M67 to turn the laser on and off, could I ask that you further modify the postprocessor to use M67 to turn the laser on (with motion) and M68 to turn the laser off immediately for traversal moves, I’m getting slight burning with traversal moves
Thanks
