Linking Document Updates to ProofHQ

One of my users got an automated email from WF saying that someone had responded to a comment he made in ProofHQ. Unfortunately, the link in the email sent him to the Updates section of the document where there is no way to open ProofHQ to see what that comment refers to (our docs often have hundreds of Editorial comments). Having a link in that Document Updates section that would open to the comment in ProofHQ woud be incredibly helpful.
