Or through some other mechanism like a conversation ID. Our old tool (Swarm) used the exact same subject line for every email, which I think Outlook and other email apps are able to use to sort all messages about a review into the various conversation views you see around these days. Review Assistant seems to constantly alter the subject line so my Review Assistant email folder is just a jumbled mess of seemingly unrelated emails. If you could add an option to not prevent this sorting from occurring (in Outlook, at least?) I think it would greatly assist most people's ability to use the tool efficiently. Otherwise the number of emails can be pretty overwhelming without a lot of tweaking.
