I have many users in Service Desk that are set to see "All Requests" as they help manage projects across multiple sites and departments. 

We are considering processing employee termination requests through service desk but are concerned with who can see these requests. It should be limited to the person submitting the request and our IT Technicians defined in Service Desk.

Is there a way to specific if using a certain template or choosing certain category that the request is private and only to be viewed by the requested and the technicans?
