I thought to share this as I haven't seen anyone writing about it before.
Last fall I called KCC to ask about a couple of things, one of them being how to postpone scheduling my interview date (my CN was current already in February).
One way obviously is to postpone submitting the DS260, but the KCC lady also told that it's also possible to submit the DS260 and then email KCC asking them simply not to schedule the interview until a certain date. Of course the interview date could be some time later than the date you tell them, but not much later as your DS260 would already be processed. Most importantly, it would not get scheduled any earlier than wanted.
