Looks great mate.
Sorry, I don't have any info as to how the door looking procedure is changed. I simply asked the dealer if it could be done and they said yes and changed it....no charge either.
Just to be clear, if I use the remote to unlock then I still need to press the button once to unlock both doors (this can't be changed, according to the dealer I use), its when I use the keyless/touch to open that it opens both doors.
