An @All or @Everyone Tag Instead of Using the People Tab

Description - Would love to have a tag to use to indicate everyone on a Project. Such as "@Everyone" or "@All"

Why is this feature important to you - Because the People tab is limited in formatting and missing all the bells and whistles of the Updates tab.

How would you like the feature to work - When putting a note into a Project, or a Task, or an Issue related to a project, I'd like to be able to put an "@All" and it tags everyone.

Current Behaviour - You have to go to the people tab to do that and you can't format the text.
