Allow Actions to change trigger severity accordingly with conditions

Problem: Today, it's not possible to configure rules/conditions for a trigger change its severity automatically after it was fired.

Example: A trigger was fired with severity "Warning". If someone wants to change its severity for severity "High", a manual action must be performed.

What is suggested: Allow to define on Actions section operations to change trigger severity according to given conditions, the same way we can send messages/alerts to users and groups.
