This feature is available via the menu choice DynamicZip ยป Import States in the DZ State Setup window.
This allows you to populate the DZ State Setup Table as a separate step from the rate & boundary import.
This doesn't have to be done, as it happens during the rate & boundary import. But by choosing to do this before you run your first rate & boundary import, you could potentially save yourself some time by avoiding the need to re-import after making changes to the DZ State Setup window.
NOTE: A message will give you the option to continue or cancel.
