I feel it would be logical when copying sections, elevations or details from one project to the next, or merging them into a project to be able to copy the 2D content within each window as well. A simple prompt like the one you get when pasting info from one section to the other is all that is required asking whether you wish to paste the 2D content of any section you might be copying/merging.
