It looks like clicking "add to map" adds a chunk size indicator to the UI
This indicator isn't centered on the given position (I tested with the Pos button) instead the square has its top left corner on where the given spot is.
Additionally it appears there are some not so obvious rules about overlaps since my testing area wouldn't show multiple. (But if that is intentional it is fine just calling it out as a thing)
