Prep For Image Capture Task

When using the prepare for image capture task I understand the SMA GUIDs are stripped, and sysprep is ran against the client.

Is an unattend file used for this sysprep?  Can we force it to use a particular unattend file?

I understand there are ways to avoid using the prepare for image capture task by doing all of your syspreping/SMA prep manually, but I am hoping to avoid this to make a clear and simple process for a tech who is trying to capture and deploy an image.
