Modify Shared Compendium organization

When you create a Shared Compendium, you can organize its content by “folder” Name & content type.
Is it possible to edit that structure after the fact?
For instance:

  • Delete a “folder” (ex: I realize after the fact that I don’t need a specific folder)
  • Rename a “folder”
  • Create a new “folder”

I suppose I could achieve a similar effect by re-creating a Shared Compendium and moving content over, but wondered if there was an easier way to edit the structure once created and populated!

Relatedly: I see that I can export / download a Shared Compendium, is there a way to import a Compendium as shared? That might be a way around this, export, modify, re-import.
