I believe this might be in development, but the ability to have different naming conventions for tickets. Often, IT Agents do not know if a ticket is an Incident or Service Request if they are not looking at the list view and relying on email to tell them about new tickets. Since we prioritize Incidents over Service Requests as far as an SLA is concerned, we would like to be able to differentiate when creating.
Example
INC103313 – Incident
REQ103314 – Request
CHA5602 - Change
PRB113 – Problem
