Have an inquiry on whether this is possible

Here is the request. 

The question whether it is possible for email template (for outbound forum posts and replies) so that each reply should be labeled whether it is a reply to an original post or to a reply on a comment to a post?

It was requested whether one way would be to distinguish the two by adding the word direct in the subject line of the notification email when someone directly replies to a comment you posted vs when someone posts to a discussion you started in general.
When someone replies to a thread you started - the notification email's subject could stay the same.
i.e. Shelby Community Topic Reply in [name of the thread]
When someone replies directly to a comment you made - the subject could have the word direct added.
i.e. Shelby Community Topic Direct Reply in [name of the thread]
