We have 3 levels of escalation in our WHD setup. Two things we are trying to achieve:
1. When a Level 2 tech escalates to Level 3, an escalation email gets sent to those in Level 3, but the ticket stays with the current Level 2 tech
2. Prevent escalation to Group Managers and Tech Leads after Level 3. The 'Escalate' button should be greyed out if it is assigned to Level 3.
