The new setting would be quite incomplete if it doesn't apply to the more general and useful duplicate-dwim as well. I can help with that but obviously want it done properly.

It's not as straightforward as when duplicating lines because the region would need to move, and it's a lot more complicated for rectangles. This may take some time to get right.

In particular, the full generality of allowing an arbitrary number to be specified adds quite some complexity here, and it's all useless gold-plating -- nobody will ever set that knob to 3, say.
