Settings in a reattached room
When you detach a room, all of the settings for the room in each profile are saved with the room. When a room is reattached, these settings are restored as they were in each profile. Any targets or search limits that were removed from the profile availability while the room was detached will be removed from the room. This included targets or search limits that were enabled for the room before the room was detached.
If the parent cascaded settings down to its child rooms before the detached room was attached, those settings are not applied to the new room until you apply them to all child rooms again.
