Allow Hipchat notifications of Confluence changes at a level more granular than by Space

Confluence allows notifications based on certain configurable activities within a space to appear in a team room in Hipchat - this is awesome! However, this isn't nearly granular enough for our teams. Please allow the setting of a virtual "root" for this purpose at a lower level than a Confluence Space. This would be super helpful, but only if we can make it more specific! Out of the teams we have here (probably ~ 30) only a handful could use this feature as it stands.
