setting max values for RGB faders

ok, so, i am attempting to set max values for the faders in the RBG, so that I can throw the fader up and it will go no higher than unity. At this point, I have to carefully look to make sure I am not peaking the channel everytime I turn the fader up. I have the editor, but can't seem to find a function that will do this for me.

thanks for your help!
