Add the "%" Chord Symbol to repeat the previous chord

Your idea

Allow the "%" as chord symbol formatting option and play the previous chord when encountered during playback.

Problem to be solved

In jazz music sheets, the "%" is often used for clarity to say "repeat previous chord".

This sign is at the same time convenient for the musician because the repetition is made really obvious and for writer, because he has not to repeat the previous chord and can experiment without having to change the chord at several places.

Today, the sign "%" can be entered as a Chord Symbol, but MuseScore doesn't play as it considers that sign as an error. And therefore pieces where chords are repeated are not played back correctly. The workaround is to retype all the chord at every repetition but then we loose all the benefits of this sign.

Prior art

iRealPro supports that sign:
