Our institution is looking to develop an interface to grant overrides to assignment start, due and cut-off dates for either individual students or a group of students. For us, this is a commonly requested feature that seems to be missing from the assignment tool and there are several similar tracker items already in existence describing the same or a similar issue:
We were looking to receive any feedback on the specification we've created (available here) to make sure any development work would suit the majority of Moodle users. We are also wanting to know if this is a problem or a feature that is commonly requested within other institutions.
This specification pulls heavily from the existing override tools within both the quiz and the lesson tool.
