Managing Requests via Email

We've been using SDP-MSP to keep track of issues and logging the time spent on issues in the Work Log area.

The trick is that our technicians are the ones that are creating the requests 99% of the time. We have it configured to automatically create requests from e-mail but it would be very helpful if our technicians could add work log entries to request via e-mail

The tech's are on the road alot and it would be much easier if requests could be managed in the following manner.

-tech sends e-mail to open a request

-request is created and the tech is notified of the new request (we already do this via business rules)

-tech does work

-tech replies to the notification message with the work done and perhaps the time spent and the request is updated with the new information.

is there any way to accomplish this or something similar? We are just getting started with SDP-MSP so i am not against changing the way we do things if means that we can manage the tickets more efficiently via e-mail

thanks.
