code: def exec_cmd(self, command, **kwargs):
          
  
          if command == 'load':
              if kwargs:
                  kwargs = dict(options=[kwargs])
          return self._exec_cmd(command, **kwargs)
docs: Normal save and load only need the command.
  
          To merge, just supply the merge and file arguments as kwargs like so:
          exec_cmd('load', merge=True, file='/path/to/file.txt')
