Does anyone have an automatted install script for import, installing PUM?

I can automat the download of all of the images from support with wget.

I can use the delivered script to extract and create the PUM image

I can use vboxmanage to import the PUM Image.

I can extract the PI_home and all of the client tools.

Anyone know how to

1. Install Change Assistant through command line?
2. Reimport Databases through command line into change assistant?
3. How to initialize the initial PUM Image boot with my preferred answers?

I would like to reduce the new image from a multiday process with a knowledgable person, to a script that can be run by nearly anyone and left alone to finish.
