How to Make Genos style voicing like FMaj7/G ie 13 sus4 (and not just F/G )

[nonchai]

  in Fingered On Bass mode what's the fingering to get the arranger to play 13 sus4 or as slash  FMaj7/G?

(dominant 13 sus4 as used in RnB/neo Soul/Gospel type music )

I mean I know how to voice this. It seems I can hear F/G in many styles ( ie F major triad over G ) but not Major 7th over G

Its a very specific sound.

On Base just produces the lowest note played in the chord as the Bass note.
  Use AI fingering for slash chords.
