When creating an assignment in Schoology, it would be helpful to have a set of checkbox options to determine the options students have available when they submit and assignment. For example, if I want to restrict an assignment submission to upload only, I should be able to uncheck the options for the student to create or pull from resources.
Another example would be if I wanted students to create their response in Schoology, I should be able to uncheck an option that would hide the upload tab.
Being able to limit "Submit Assignment" options available to students would significantly help to minimize student confusion (aka. not following directions)
