Is there a way to bulk edit the hierarchy? If not is there a way that when I import points via Excel I can tell it what folders it belongs to?
Bulk edit Point Hierarchy
In the upcoming release we put a "path" property into the data point's JSON that is /path/to/folder for the import/export tool and endpoints, but not into the CSV.
I can write a little python script here, if you like, that converts a CSV with a /path/to/folder column into a hierarchy JSON, if you would like.
Edit: It will probably be added into the CSV model in 3.4, but I have no projection when that will be as we're trying to wrap 3.3 up currently.
