At present, new items can be scheduled for publishing - but existing published items cannot be scheduled.
If a current published item requires a content update, and that update is not permitted to go live until a certain date/time - then this update must be done manually at that date/time, which is not always possible.
Having the ability to schedule publishing for previously published items would greatly improve workflow and save time.
I 100% second this feature!
