PlanetCNC E-Stop Event - switch off single Output

Hi,
Does anyone know if it is possible to add another selection under the 'E-Stop' 'Events' in the settinigs. I would like to be able to get a single output to turn off when the E-stop is triggered, to my understanding there is this option but it is to turn off all the Outputs. Currently there is a option to get the E-stop event to turn off Spindle, Mist and Flood Coolant, I would like to see if it is possible just to select one of the other outputs but not them all. Any ideas?
