Saving custom keyconfigs on steam games?

[two_zero]

So man question is, is there any way I can save a custom keyconfig in a steam game (TF2 more specifically), other than saving it directly in the config? ea, that I can save it so I say can switch between my custom one and the default without having to remap every key every time I want to switch to the custom one?

 

The problem is that I am running a custom layout rather than the standard qwerty layout on my keyboard at home.. meaning I have to remap every key on my keyboard every time I get a new game. That in it self is no problem, but now I find myself only having access to another persons computer during a few weeks, and when I opened TF2, the settings seams to be saved on steam, meaning the keyconfig is one that is meant for my custom layout. I could just reverse to default, but that means when I get home I have to remap every key again, and this will happen every time.

 

Guess I could just make a separate account since I mainly play TF, that is free (shame I wont be able to use my favorite weapon thou, but ohwell!), but it would be great to find a solution as well^^
