Use of design parameter 'MTYP' in staad connect - AISC 360-16

Can any body pls guide me if the design parameter 'MTYP' (in staad connect for AISC 360-16) is to be applied only for beams and columns which are part of  an OMF or  OCBF ? and not applied to other members ?

Thanks in advance for your help.
