In Ss2 and Earlier, if we were tasked with looking at alternate designs, we could copy a corridor with a new name and then modify the copy. Also, on occasion it has been necessary to split a corridor into two so that target alignments/features that loop do not result in multiple solutions. Again, that was accomplished by copying the corridor and changing the start and stop stations so one ended where the other began.
So how can one accomplish this in Ss4? Is it only possible using a Save As to another file? If so, we may need a CR to provide tools for copying or migrating civil objects within files or to other files.
