Our Admins are Technicians for our Internal IT Department. Our JitBit Helpdesk is used across all our organisations corporate services for tickets e.g. HR, Payroll, Finance Requests.
While Admins should be able to see all tickets for all categories, we would like them not to appear as Techs in ticket categories they do have access to manage the queue of. This prevents Admins being assigned tickets for other departments.
It sounds like this already exists. You want Admin--> General --> Only administrators can assign tickets to other administrators.
If they are Techs in the IT Queue they are still able to assign tickets to each other and they won't appear in the queues they are not Techs in even if they are admins.
