I don't think you can use the fob to open both doors at the same time. You still have to press the unlock button twice, and I don't believe that is a reprogrammable option.
The passenger door is now set to open each time I open my door handle. I kinda like this, and am not as concerned about an intruder. I thought about bringing it up to the dealership when I take the car in, but I like this too much......
It is programable to open all doors when you touch either handle with the fob in your pocket. It was done when I took delivery, I think it was accomplished by holding down lock and unlock at the same time until it beeps
