Cloudinary integration on Ghost(Pro)?

Is there a way to use Cloudinary as CDN for a Ghost blog on Ghost(Pro)?

Cloudinary can be used via the Fetch API on Ghost(Pro), but not as a storage adapter, details here:

I wanted to use it as a storage adapter. So to use images from other sources like embedding images stored on Cloudinary is working, but not the direct upload from the editor.
