Turbo Levo Mode Control

Let's face it it, trying to change power modes on the down tube while you're moving is dangerous. I see the 2018 Levos have it on the handlebar (where it should have been in the first place). Can this upgrade be put on earlier year models(2017 in my case)?
 
I found a solution, so I don't have to buy a Garmin. I just found out today the Mission Control App can change the modes on the fly in the mode screen. I will get a mount for my iPhone and that should do it.
