Option to not send 'Review has been completed' email to requester upon completing a review

We find there are many occasions when we have emailed a requestor of a review regarding the list. This is often because we are querying the existence of a list as it is a duplicate copy - a consequence of the 'copy list' function being used inappropriately!

We then subsequently complete the review and archive the list.

We would like to have the option to not send the 'Review has been completed' email that is automatically generated when completing the review. This creates unnecessary email traffic for academics and can lead to confusion.

The default could still be to send the email, but we would like to see a tick box included to select when not sending such a message is desired.
