We miss the ability to create, edit, delete document-sets in SharePoint. (Working with Document-sets in SharePoint).
Also the option to update metadata on document-sets should be nice.
I couldn't find any ideas about creating/maintaining document-sets with Flow at all.
Maybe create a web service to do that. Then call the service with http request in flow.
I would like to be able to create a flow where an item in a list triggers the creation of a document set using the metadata from the list.
I would like to be able to move a document set using flow. Move , Copy or update a Document Set .
