I don't believe there is a way to do this in the DNAC GUI. What you can do to save some time is export hierarchy in the GUI, copy and rename the areas in the CSV file and import it to the hierarchy in the GUI. Note that this will only create new areas in the hierarchy, not actually move any areas/devices/IP pools etc.
Happy to help! Please mark as helpful/solution if applicable.
