Multiplayer Save/Load Code Maps

Is it possible to create 2 maps with heroes that transfer over?
Like I complete map A, and I allow players to save their hero and load them in map B.
Has this been done? And if not, can it be done?

Here's a tutorial: http://www.wc3campaigns.net/showthread.php?t=78969

I'm sure there's plenty more out there, it's a pretty common thing to do.

heh, Yep it's been done. CoT RPG and CoT PoM RPG had that feature. (though those are fairly old, and there are probably much more efficient save codes by now). If you can't get through the tutorial I have a premade code from neostorm that can simply be edited to suit your map. (it has all the directions to do so as well).
