We have three Service Management projects and I can't find a way to change which fields are included in the notification email that goes out when an issue is created (not for the customer - the one for the Service Desk Agents & admins). It's pulling in a field called 'Priority' which we don't use (we have a custom 'severity' field), and so is causing a lot of confusion about business priority. How can I edit which fields get populated in the email?
