I might have missed it in the archive of wonderful ideas that is thwack but will it ever be possible to have dependencies within the same group of nodes? Currently we maintain a group of nodes to include the WAN carrier, boundary topology, and local LAN and I'm repeatedly asked to try and tier the application data to maximize visibility of the down node (say the WAN device) and not have the entire location show down/down (the operations guys lose their mind when they see all that red).
