Optional ability to pre/append text onto nickname based on when a role is assigned to the user.

I had a search and couldn't find a suggestion for this.

I'd love the ability to, when setting up a role, there could be an optional argument that allows you, when assigning the role, to pre/append text onto the persons nickname.

For example:
Role is called: Alliance Member

Append Text: [ALL]

When assigned to user: nickname + [ALL]
