is it possible (with a plugin, I guess) to set the start and end date of a quiz based not on a fixed date (f.i. from Nov-20 to Nove-25) but relative to the time a user started it (f.i. start date is the moment a user starts the attempt and end date X hours later).
The context is that our courses are always visible, and each learner enrolls at a different moment, so our quizzes cannot have any end date. But we would like to have the functionality of seeing different types of reviews when a quiz is open and when a quiz is closed.
