turn faders on and off with macro

i made 2 macro;s: hazer on and off. 

when the macro starts the faders go to the intensity level i told the macro to go. 

what i want: i have 3 faders 

1 -  fan 

2 -  fan (hazer) 

3 -  haze  

when i put my fader on 40% i would like to turn on and off the fader instead of the intensity of the selected channels.

is that possible with macro?
