Alert Acknowledgement Template edit

The alert acknowledgement email template seems to be the only one not available for editing in the settings section.  It would be nice to add ##GROUP## to the subject line to match the initial alert and alert cleared email.  The ack emails don't seem to list the group in the subject or body of the email making it difficult to search emails.  You need to search based on the alert ID or IP address rather than being able to search by group.  I find people search by group because that is included on all other emails and then have to help them understand why the ack emails aren't included in their search results.

If there is some other way to accomplish adding ##GROUP## to the ack email template let me know.  Hopefully this is an easy fix.  Thank you!
