Upload Multiple Documents At The Same Time

Maybe there is a function for this that i just haven't found yet but every time i try to upload multiple documents to a single folder the second upload will just replace the first upload. It would save a lot of time if we could drag multiple documents into the upload box and upload them at the same time. We are also familiar with onvio, and you are able to 'print' the document to wherever you need it to go, which saves having to save it and then upload, and then delete. This would be a fab option to have as we wouldn't need to save the document individually first.
