How make arpeggio span two staves?
I am trying to make an arpeggio symbol span both staves of a chord as shown here:
If I select the whole chord and double-click the Arpeggio symbol Musescore adds two separate symbols, one for each stave.
I know I can just hide one of these and extend the other so that cosmetically it spans both staves, but I think that on playback the two arpeggios are sounding at the same time, which is not quite the correct effect.
I have tried entering all notes into the lower staff then moving some of them from one staff to the other as per https://musescore.org/en/handbook/cross-staff-beaming but that moves the whole chord.
Is there a way of moving the attachment of the top (or bottom) of the arpeggio so it truly covers all the notes in the chord?
