It would be incredibly convenient for my workflow if I could download student's assignments with the file name amended to include the student's email (as in Homework_1_luca@ucsc.edu.pdf ) rather than the Canvas ID.  The student email is for me a better identifier, because it is something available also in the Registrar system of my university.  Furthermore, the email is also an ID that works for Google Apps and Drive, so if I need to use Google Forms, send the student email, share feedback on Drive, I can all do it more easily.

At present, I am asking students to submit the homework on Google Forms, which collects email addresses, as a workaround, but it would be much nicer if I could get the same information from Canvas.
