key fob (re)configuration

I've looked around and found out how to change the behavior of SKS unlocking depending on which door you open first. But I want to change how the unlock button on the remote works! My manual (2007) says it can be done, and to ask at the dealer. Is there a magic dance to do, or does this require a dealer tool?

The default logic of the remote alone is ok... the default logic of the SKS is ok. But if I have SKS, why would I ever want to use the button to unlock only the driver's door? I can do that with SKS. I'd like to leave the SKS at its defaults but change the remote so that one press of the unlock button unlocks everything. SKS is perfect when I'm alone, but when someone is along with me I get tired of having to do the double-push on the unlock button. Half the time they are yanking on the passenger door handle before I can even get the doors unlocked.
