How do I prohibit multiple-file submissions? I want students to submit ONE PDF file for grading, but some are scattering their work across multiple files. Can I get Canvas to enforce a single-file limit, while still allowing students to do multiple submissions (replacing the single file)?
I do restrict to PDF only, but Canvas allows them to submit multiple PDF files, and I have been unable to find a way to get Canvas to limit them to one file. There might be a way, since Canvas has a terribly uninituitive interface, with things hidden in surprising places.
