Auto-confirmation emails

This request is two fold. Fist, we want use the auto-confirmation feature, but we do not want the builder to be able to reschedule the work. Could it be possible for the requested reschedule date to come in as a request but NOT to move the work on our calendar? Sceond, it would be nice to be able to review a report of responses, whether confirmed or requested to reschedule, then move the reschedule requests as we see fit.
