Add ability to set comment via email by agents to Internal Comment

Problem Definition

Currently , all comment added via email is automatically set as public.

Suggested Solution

There should be an option that allows:-

1. The ability to decide default behavior (internal/public) of incoming email based off of group/role in a project
2. The ability to decide behavior (internal/public) of incoming email based off of tags (#internal or :internal)

Current Workaround

Using Automation create a rule with the following components for the user belong to group/role:
Trigger: Issue commented.
Condition: Initiator is in role/group
Action: Edit comment > Comment to edit: Trigger Comment ; Comment Visibility: Internal Only.

Using Automation create a rule with the following components for the tags (ie tag :internal):
Trigger: Issue commented.
Condition: Advanced compare condition: comment contains :internal
Action: Edit comment > Comment to edit: Trigger Comment ; Comment Visibility: Internal Only.

Trigger: Issue commented.
Condition: Initiator is not a customer
Action: Edit comment > Comment to edit: Trigger Comment ; Comment Visibility: Internal Only.
