Option to disable/redirect @here and/or @all in rooms

At our company we have "Support" rooms in hipchat, these are rooms where 300+ users are hanging and asking support. These rooms have Engineers On Duty (EoD) hanging there to answer support questions. Doing an @here or @all here by people other than the EoDs is very irritating to the users who hang there for their support questions.

To solve this, I have two suggestions:

1. Make it possible to completely disable @here and @all usage in specific rooms, configured per room
2. Make it possible to redirect the @here and @all usage to a specific set of users (one or more), and skipping the normal notifications to here and all users in the room. So only notifying the users where the @here and @all is redirected to.
   Would be even more awesome, if, when the people where the @here and @all is redirected to, do a @here/@all, that those messages are actually sent to the whole room users group. As those people manage the room (eg. for sending maintainance messages)

I found similar suggestions (HCPUB-789, HCPUB-1495, HCPUB-513, HCPUB-1162, HCPUB-1436, HCPUB-1665), but as I also have the suggestion to redirect to a specific group of users, I still created a new suggestion for this
