When setting an assignment, setting, collecting and returning work in teams - it works fine.
But it using teams to set work collected, or marked, by other means - the task can hang around.
I could delete the task (losing history) or return the task (giving spam to the students).
A way to transfer to archive without 'returning' would be nice. And it'd be *really* nice if there were a default (e.g. 2 weeks after submission date, archive this task unless I over-ride - perhaps extend 'start' 'due' 'close' with 'archive on').
