How can i Bulk import of all Attributes fields into a newly created Group with Dynamic Drop Down from a Previous group that had some configuration error. Keep in mind i work around by export the attributes first in CSV  then import them to a newly created group but i need all the attributes and fields same. All this is in CLM. Any help would be Appreciated.
