Do any of you guys that run an air ride trailer have the air dump in the cab?

I just purchased a new trailer with air ride and I would like to dump the bags when I unload.   Maybe I don't have to? 

I know there was a disscusion here a week or two ago on this, but there really was no answer. So, if you have put a switch in the cab, I would like to know how you did it, and better yet if I don't have to dump the bags that would save alot of extra work.
