Notification option "after all successful builds", not on failure

We have a plan in bamboo to update a staging environment.
Many users within the organization are waiting to check out what their favorite new feature or fix looks like in staging.

I'd like to send a notification to hipchat every time there is a new staging build ready for them to work on. I don't want to send the notification if the build broke. Currently I see no such option in Bamoo's list of events that can trigger a notification.
