Is there a way to uninstall a patch with Steam?

I curently have FM2010 installed via Steam, and want to delete the patches, but keep the game installed via Steam, as I use the 2009 skin. I don't want to delete them because of the DB because i know there is an option to change the DB you use, I'm not that stupid, I just want a couple of things that were in the old patches but not in the new ones, such as when you copy a saved note into word or something else, there isn't all of the annoying code inbetween and missing word, it says what it said.

I dont use steam but believe that there is an option to disable automatic updating.
