Reducing number of chord diagrams at top of flow

It’s a workaround, but you can do this with MusGlyphs.

  1. Make sure Font Style / Chord Symbol Font is set to MusGlyphs and enter the chords you want to appear at the start of the piece.
  2. Use Shift-X, select MusGlyphs as the font and enter the remaining Chords
  3. Align and resize as necessary.
