Follow-up on Polichords (Stacked Chords)

This is a follow-up on the post "https://musescore.org/en/node/268099".
Please add these Polichords so we can write Liberated Dissonance in clean notation. All they are is a chord symbol on top of another separated by a line and the most anyone will have is three chords stacked. It is unarguably an expansion of the limit for musescore.
