Unlocking passenger door behind driver

Lately I've found it very annoying not to be able to unlock the passenger door behind the driver. I have the Prius v 5 and all the doors open except for that one. I find this kind of strange because many times I'll have a bag that I want to place in the back seat. So I'm wondering, is it possible to unlock this door using just the drivers door handle? I have already gone through some settings on my screen under vehicle, but can't find a way to change it. Anyone out there know if it is possible to get all the Prius doors to open with one simple grasp of the handle? If so could you go through it step by step?

 

I learned from another blog site that if you hold down both the unlock and lock buttons (on the square remote control) at the same time, and wait for the car to beep at you, that will change the door setting from only unlocking the drivers door to unlocking all four doors plus the hatch. When you think about it, it makes sense to have that as an easy changeable option. If you were alone in a parking ramp, you probably wouldn't want all the doors to open at once. But if your from a little town in Wisconsin, you most likely would like the convenience of having all the doors open at the same time. I believe it should work for all the Prius v models.
