The current method of grouping devices together in NCM is useful to a point, but is fairly labour intensive to manage and deploy. I'd like to see a grouping system similar to that of NPM, perhaps even for NCM to use the actual NPM group structures.
For me, I'd like to group devices together by region, then by a Building Category (e.g. If building is 24 hour, or just business hours). This would hugely help my vision of using NCM to rollout bulk config changes for a very large Government organisation.
