It doesn't seem possible to do so as an Admin @Host Ever or it's because we're on Pro plan and not on Business/Entreprise Grid.
But are we 100% sure we can customize banners? From this help article, I'm unsure if it's just for telling Guests/Users who can see their messages, or if we can leverage it as we want
