The Media Storage API and MCP can't move existing files or folders into another folder; the single and bulk update endpoints only rename. Passing returns "updated: true", but nothing moves. Re-uploading creates a new URL, which breaks live emails that use the original. Please support on the single and bulk update endpoints so files and folders can be moved without changing their URL. Please also return an error when an unsupported field is sent, instead of a false success. Use case: about 180 holiday email campaigns and roughly 900 images to organize into folders.
