Great puzzle. And I'll echo Mihel in saying that by telling us how to copy cells from the puzzle you're a hero.

Great puzzle Flinty. This has a beautiful flow and nice logic elements.
By the way, with your friendly note in solution code, you are officially my super hero of the week (Sven being the one of the decade)
