Custom Priorities
You can add Custom Priorities to your tickets under "Admin > Custom priorities".
Custom priority levels are user-defined categorizations that help support teams identify and sort tickets based on their importance and required response time. Unlike standard priority levels, custom levels offer flexibility to align with specific business needs.
The default ticket priority levels are "Low", "Normal", "High" and "Critical". This is enough for most people.
To create a custom priority level simply enter a name and hit "Add".
