Fine-grained access for WebDAV?

Need Answer

Is there any way to limit what folders can be accessed with a specific WebDAV app password? I'd like to use my mailbox drive for syncing some browser addon data, but it seems any of the generated passwords allows to access the whole drive, and I don't feel comfortable allowing that to a browser addon. I know to encrypt all sensitive data but I'd like to minimize the risk anyway.
