I have a problem that I'm hoping someone out there can help with.

Two of my friends and I each have a Wii with our Tiger Woods character on our own systems. How can we update each others systems with the current level of our character?
It seems kind of odd that they would create this game without a way to do that, but then again, if they would have made T.W. playable over the net, I wouldn't have this problem.

Any and all thoughts are appreciated!
