You can set the Windows version for a particular exe file (similar to the compatibility mode on Windows), but this method is not quite as complete as the per-prefix setting.
Since all games offered through steam presumably run correctly in Windows XP or greater, you should file a bug if a steam game does not run correctly with Wine configured to report Windows XP or greater.
