Chord symbol placement over lower staff of accordeon

Hi all, how do I place this chord symbol over the left hand of the accordion (where I imagine it belongs)?

Depending on whether you have chord symbols for other instruments, you could either set the Layout Options>Chord Symbols to position chord symbols between grand staff staves, or you could select all chord symbols for the accordion and use the property in Engrave mode to reposition them.

Phew, no other chord symbol instruments so I will go ahead with the first option in this score, rather than click and drag.

With @Janus’s option #2, you wouldn’t have to click and drag - as he wrote, there’s a setting in Properties that places the chord symbols under the staff (which in this case would put them between the staves).
