Our course is building on the previous assignments, so I would like/need to be able to submit multiple files from a previous assignment with the latest one (e.g. assignments 2 and 3 have source files that I want to include as attachments/submissions to assignment 4) When I try and do this, I find a link that says "click here to find a file you've already uploaded" but it only allows selecting a single file, not the multiple files I want to attach to the assignment submission. No combination of alt/ctrl/shift clicks seems to offer a way to select multiple files from the dropdown list of previously uploaded files provided so I'm at a loss as to how to get my file submissions collected for the assignment. Re-uploading the file creates a suffix (-1, -2, ...) to the filenames which won't work well for this since these are Java source files and file names are important. Anyone have any ideas on how to dance around this problem with the assignment submission interface?
