Linked Incident Request Control
Currently when you link multiple tickets all pertaining to the same root issue, you can add a resolution to the main incident and SDP gives you the option to apply that resolution to all of the linked incidents. The problem is that when you select the drop down to update the status of the ticket to "resolved" it only changes the current ticket you are viewing and does not update the status of the other linked incidents, so you still have to manually view each of the linked incidents and change their status to resolved.
This defeats part of the purpose of linking incidents together, you should be able to update/edit/modify all of the linked incidents as if they were one incident.
