Save Game Location Question

[Warmskin]

I would like to install this game another time on the same computer. The reason is that my wife would like to try it but her own machine would not be able to handle it, I'm sure (even though the req's are pretty low). And the way the save sames are displayed in the game, I believe would become quite a mess in a short amount of time. Her saved games mixed in with mine would definitely become a problem. But, I find that the saves are put into a special folder. I'm afraid that even with the second game install, it would still put the saves into that same folder. Is there a way to change where the game puts the saves? I remember in the demo it asked me where I wanted the saves. It didn't give me that option when I installed the whole game (dvd vers.) Or, am I missing something here? Thanks.
