Assign Variable to Secondary Dimension TP of FCF

Hello,
I tried looking for it on this forum, but couldn't find a solution.

I have a Xact measure FCF with primary and secondary dimensions. I can easily assign the TP of the primary dimension with 'Assign/V1=FCFLOC5.TP.MEAS'.
My question is, how do I get the TP of the secondary dimension?

FCFLOC5 =POSITION : CYL4
FEATCTRLFRAME/SHOWNOMS=NO,SHOWPARAMS=YES,SHOWEXPANDED=NO
CADGRAPH=OFF,REPORTGRAPH=OFF,TEXT=OFF,MULT=10.00,A RROWDENSITY=100,OUTPUT=BOTH,UNITS=MM
COMPOSITE=NO,FIT TO DATUMS=NO,DEV PERPEN CENTERLINE=OFF,OUTPUT ALIGNMENT=Datum Reference Frame
CUSTOMIZED DRF=NO

PRIMARY DIMENSION/POSITION,DIAMETER,0.25,MMC,,,A,B,C
SECONDARY DIMENSION/POSITION,DIAMETER,0.1,MMC,,0,,,
