WDS and capturing unique images

question:  I have 40 field technicians in the field with notebook computers.

I want to capture an image of each of the 40 unique notebooks.  by unique, I mean I want to capture user data, outlook settings, etc so if the notebook blows up, I can push his image to a new notebook and ship it out.

someone is telling me that WDS won't capture a unique image and that each image will be wiped and start over.

Can I do what I want with WDS?  Can I capture unique images with WDS and then when notebook 21 dies, shoot image 21 to a new notebook and ship it out?

I know I have to put in the key an all, but won't that work?

Thanks
