Remove content of replies inside emails?

Sam, in our case, it’s a closed (not public) community of medical professionals, sometimes discussing sensitive cases etc, so we don’t want any content/details in the body of notification emails, but the topic titles rarely have any sensitive content. I have been asked if I can show the topic titles in the notification emails because members are more interested in responding quickly to some topic more than others, but they currently can’t tell by just the Topic #ID in the subject.

I also thought of disabling the ‘private email’ setting and editing the email templates instead, but there are several of them - I’m not sure if that would cover all cases - and there doesn’t seem to be a ‘digest’ email template(?) so I’m concerned that would still show the post contents.
