The databases are built to support comprehensive editing functionality. We have basically made every entity and field in the database editable. So, this case will be possible, along with many, many more things that you might want to do.
Full editing functionality will not be available not immediately at launch. With such a rich metadata model, the editing user interface has a immense amount of surface area–getting that UI built and polished just didn’t fit in to our launch schedule. Until that work is done, Roon will support several editing flows focused on correcting mistakes or shortcomings in automated metadata retrieval.
