Easily Save Attachments Thru Drag And Drop

I need a way to more easily save attachments from Asana without having to open the document. A drag and drop function would be great to save attachments from Asana to my computer. I would also want to more easily move attachments from task to task across projects. I understand I can use an @mention to reference the other task, but I want to save my team a step and just give them a document in the attachments of the task they are working on without having to open up a separate task to find a document.
