Not sure I fully understand. I do it manually when creating new configurations. I don't know of any way to copy all in bulk. Also, they won't be linked to each other. So, we have to edit and reconnect them to each other.
Navigate to Templates at the Site or Org, depending on where you want to build the new configuration.
Choose the template type you want to export from the drop down (e.g. Life Cycle Templates).
Right click on any particular PTC Life Cycle Template > Save As > and give it a new name.
