Server pinging

At the moment, im pretty sure you cant make it in server settings so that members can only ping certain roles. In the settings, you can allow certain people to ping any role they want to. I want it to change, so i can make some people be able to ping certain roles and not others. For example, be able to allow said server-member (that isnt a staff member) to ping @Events without also being able to freely ping @everyone in the server.
