CMS - Azure Storage for Assets files

Hi

I have searched documentation but cant find any example and wonder.

1) Is it possible to use Azure Storage (Blob or File) to store assets files like pdf, docx  i.e files that editor could upload and reference?

If its possible:

1.1) Is it possible to structure uploaded files in "catalogues" in Epi edit mode. As I know Blob storage in Azure is kind of a flat structure but maybe you could use Container as a catalogue or? 

1.2) Is it possible to use ACLs for files so you can filter files based on logged in user/editor?

Thanks!
