Fs Commander flight plans

Have updated AIRAC data for all my addons. I’m using FS commander to create flight plans an then manually typing into PMDG and Flight 1 ATR FMC. SIDS AND STARS in FS commander don’t exist in the aforementioned aircraft FMC s.
I’ve given up trying to import the flight plans directly from FS Commander to FMCs as can’t work it out.
Many thanks for any tips.
Apologies if this is somewhere in the forum but I HAVE looked.
