vLite all Vista editions on single disc?

[g3brown]

I use 2 original Vista SP2 OEM disks to load various PC with Vista, a 32-bit disk and a 64-bit disk. I would like to use the Tweak and Unattended sections of vLite so I can walk away from computer during the installation. Is it possible to keep all editions on the image (Ultimate, Home Premium, etc) and still use the tweak and unattended features? So far when I edit an image and save the ISO image, it seems it is removing the other versions. The end result I want to be able to select the edition of Vista I choose and then it run unattended and apply tweaks subsequently. I don't want to have to make multiple images for each Vista edition. Having the 32-bit and 64-bit disc seperate is fine, but would be a plus if I could combine them as well.
