Start anywhere modeling in Discovery 11 allows us to quickly pull together and model technical services, but the dynamic model updates on a busy network means constant model reviews. When a model is updated we have an option to 'Accept Changes', but in almost all scenarios we have seen, we would prefer to revert to the previous model. We are seeing many SI's/Candidate SI's, and hosts being pulled in through the underlying infra tools (Patrol, etc) which are not at all relevant to the application model. Can we include an option to 'Reject Changes'? While I'm at it.. an option to 'lock' the model once we are happy it's accurate would also be useful.
