seperate autounattend.xml for EACH vista version

[Rasengan]

Here's the deal, I have WinBeta's AIO Vista disc, and my list of Vista keys from TechNet.

I want to know if it's possible to set a different script for wach version, say I pick home, it installs with the home key, or the ultimate key for ultimate.

If this can be done, please, tell me how!!
