Driver-side assist grip
 

For the current generation 4Runner, does anyone know (or has this already been addressed) if there is a factory driver-side assist grip that can be added. Toyota has gotten into a bad habit of not including them on any current generation truck or the 4Runner, just the Land Cruiser. I'm thinking about going from a 2013 Tundra (which has one) to a new 4Runner but can't stand not having an assist grip.

Thanks!
