megan, yes I'm a controller. If you're asking is there some form of ops control then the answer is there is none. Whoever receives the information is responsible for dealing with it appropriately - if it comes from briefing it would be via the flight data coordinator and they'll either add the info themselves or call the controlling sector who will do it. If you tell us via radio the controller will edit the flight plan accordingly (the active version in TAAATS not what you sent to the briefing office or NAIPS) or pass it on to whoever needs to know.
