Is it possible for my students to upload a Document/ppx/xlx and then work on the Document afterwards. Currently from what I see they download a document that I have set for them. Work on the doc, and then save somewhere else until finished and then upload. My problems is students that have school loan computers and the consistent loss of work because they have a different laptop each day. Even if it is possible to save to one drive through canvas, but I cannot work out how.
