Update docs to explain how to add custom bass clef key signature
When following the instructions in the docs: https://musescore.org/en/handbook/key-signatures#custom-key-signatures to create a new key signature in the treble clef and then dragging it onto my score I see it doesn't put the correct flats automatically in the bass clef signature. Nor can I see any way in the app or docs for how to make a custom bass key signature. (See the attached screen capture).
Please will you update the app or docs to explain how to do this.
