I could do that...but then I lose easy access to the assistant. I could set up the tap on back function, but that doesn't work when it's in a holder in the car. There are no options that I can find that would let me assign the assistant to open on power + vol up. Unfortunately these phones aren't as customizable as as I'd like them to be. Or at least not by default, but I don't want to go through the trouble of flashing a new OS yet.
