For classic data model, the UI can roll up timeseries from all children, which is a very useful function allowing you to reduce the amount of traversing to find all relevant timeseries. This functionality seems to be missing for data modelling. Is this functionality missing, or is it a particular requirement to the data model that we have not met in our model?
It would be good to either document better how to make this happen with data modelling, or reintroduce it if it is missing.
