Currently we can edit the Agent Notification when a note is added to a ticket which by default includes a link to the originating ticket. However, the template does not apply to replies to that note.
Thanks to the template, the ticket number is in the subject line by default but a link would be more convenient. It’s possible that if a reply takes too long or there are many pertinent notes the reply might reference it can be confusing. (For at least one of my agents!)
