It is usfeul to schedule the release of assignments in future using the 'available from' features, but I would also like to be able to customise the visibility of certain details until the assignment becomes available, such as:

1. "Make all details unavailable until assignment becomes available" (current option only)

2. "Only 'available from' and due date is visible until assignment becomes available"

3. "All details visible including due date and assignment description, only 'start assignment' button is not visible until assignment becomes available"
