Add bulk content upload option#5

Please add bulk content upload option in the asset library.

This is a very needed option, its so difficult uploading media one after the order. SInce over 3 years now, you should make this available as soon as possible

Please add to bulk upload the content or even the PDF files should be bulk uploaded because it is very tiering if we have some contents to be uploaded via multiple files it is really time consuming and frustrating to upload each and every time
