I do not think this is possible in 2k3.
To do this, you would need the ability to teleport events, which i do not think is one of the commands.
If there is, It's probably possible. You'd just need a common event and some way of tracking therein. (It would probably be the same as the positioning system i'm assuming is in the tutorial.)
If it's possible and you need help eventing, then PM me or something. If it isn't possible, sorry then
