Cancel print gcode?

I don’t see anywhere to customize what happens when a print is cancelled. Only reason I was looking because the default cancel gcode does not perform a:

M960 S5 P0 ; turn off logo lamp

So the logo led on the print head stays on forever until you reboot the printer or successfully finish a print… No big deal, but fixing this I thought would be no big deal either… but seems it can’t be done. In the meantime I created an alternative profile and changed the start gcode to turn off the lamp instead. then i send something random to the printer and just cancel it as soon as the led turns off.
