How to add structural spec

I have created structural cata and want to add that to spec so that it would appear in design modify section command.

How to add it I have prepared specon file which read like

$S-              
 $(  BORE  UNITS  MM  $)      
 $(  DISTANCE  UNITS  MM  $)      
               
 OLD SPECIFICATION  /BS-SPEC          
 MATREF =0
 FLUREF =0
 RATING 0.000
 LINETYPE NUL
                 
 HEADING              
TYPE NAME STYP GRADE DEPTH WIDTH WEIGHT INERTIA CATREF
C */100x50x10PFC PFC 43 200 150 47 2376 /100x50x10PFC

I have to add this channel.
