I know its not the same thing, but you can use AE Button Plus (awesome app) to assign this to most of the special function hard buttons on your 6800. For example, I have my comm manager button (one under power) to launch the comm manager on a single click. I have it set to toggle the sound/vibrate mode if I press and hold it.
I checked and AE Button plus will not remap the wifi slider, so you would need to choose another button like I did.
