Instead of adding to the "Deferred Submissions" by hand, it would be great if on the moderator screen we had a button "Defer Submission" which put that submission onto a queue to wait until more information was available. Ideally, it would put it in a queue much like the "Submissions" queue, so that returning to that queue occasionally to look at deferred submissions would be easy to do.

As per a recent Moderator Noticeboard discussion, this was felt to be a low priority.
Changing the priority to 2 since 1 is the lowest and 10 is the highest priority.
