Can Bootcamp Assistant cache its support files?

Question

I'm needing to run the Bootcamp Assistant several times to get the right Windows installation working with my machine, so I keep needing Bootcamp Assistant to build a new USB bootable installer. EVERY time I do this, it insists on downloading the "Windows support software". Over a gig.
...I know which installer package I need; I've downloaded it myself. Is there any way to get Bootcamp Assistant to cache the support software download so it doesn't need to fetch it every time?

Answer 1

Is this the correct model? I would not recommend Vista drivers on Windows 7. You can download these in .zip format and put them on a FAT32 USB flash drive and unzip these.
