Feature Request: Option to not send emails

We often enter support calls into SD+ that are simple questions or requests that are resolved during the call. However, when the technician enters the request into SD+ and then enters the resolution it sends 2 email notifications to the client for a request that has already been completed and closed. If we had SD+ set to email them when a request is closed it would send 3 emails.

There should be an option or checkbox on the request entry page to disable email notifications on a "per request" basis when entered by a technician. This would help reduce email volume and keep users from receiving needless emails. I still want them to get emails when they enter requests themselves.
