Is it possible to set a fade time to the clear button?

I have seen it done on a GIO and it was so nice not to have the hard out while programming with clients on stage or in the room.  I have looked in the control panel and user settings but if that feature is there, I can’t find it.  If it does not exist yet would anyone else find this helpful or see the value in smooth outs always when clearing out the programmer?  Please forgive me if I am missing the obvious. It would not be the first time
