Hi All,
I found this thread while looking for a solution to the OP's questions. Looks like that since the solution above was suggested, a new work around is available. You can "save" a section that you want to copy/move (click on the heart in the pop-up when you click on that section), and then when you go to add a section on the page you want to move/copy it to, you can choose from your saved sections. Works a charm.
