When I receive an email from a directed update on a proof, it's impossible to track the mention back to a particular comment on the proof, especially when there are hundreds of comments on a proof. The email takes you to the document comments, not the proof comments. it is possible to include the comment # - such as COMMENT #17 - on the email for the @mention? It would be great to reference the comment number, rather than spending time finding it on the proof.
