wine users - Jan 2012 - cmd line parameter to set windows version?

Maybe I have overlooked this in the docu, but I'd like to know if there is a
command line option to set the windows version, like eg.
wine --version=98 "c:\\foo\\bar\\spam.exe"
wine --version=xp "d:\\honk.exe"

I am asking because I have quite a lot of windows software (ie., games) that has
buggy installers and/or core engines, and switching the wine default version
*every* time until I have installed them all and have set the versions to use
would be a bit tedious.

	It is possible to set it from command line (for example, "winetricks
winxp"
or "winetricks win98"), but it is better to install each program in
its own
Wine prefix (for example, "~/wine/mygame" or
"~/wine/microsoft-office").
Reasons are obvious: you can uninstall a program by deleting its prefix, you 
can apply application-specific workarounds without affecting other programs, 
and everything will work more reliably this way.
