Description - The ability the "Cancel" a proof and have everyone on the proof route get an email notification that the review is canceled, and the proof is removed from their queue.
How would you like the feature to work - Have a "Cancel Review" button that generates an email notification to everyone on the proof route saying the proof is canceled. Also removing those proofs from their queues.
Current Behaviour - If someone makes a mistake and uploads a proof review (attached the incorrect document, etc.) they have to switch all the reviewers and approvers to just reviewers to remove it from their queues, and send out a mass email saying "disregard this proof, mistake made" or something along those lines. Way more work than just clicking a "Cancel" button and the email automatically generating.
