Hi !! 
I need to know if there is a possibilitty, usign the Shopify default media uploader or by an App, to upload a File (Image, Video or PDF) and assign a tag to it. 
I want to filter the files by the tag assigned to them.
The files are not relationated with any Product, Order or Customer. Its a simply File uploaded. 

How can I reach it ?
