Place chord legend at top of score

In GuitarPro 7, fretboard diagrams are automatically grouped at the top of the score. This allows the composer to group all their chords at the top of the page and then use simple chord symbols above bars.

I am trying to replicate this in Musescore 4 without success.

I was following this support thread https://musescore.org/en/node/306424 but turning off Auto Placement (updated to Auto-place in Musescore 4) does not allow the fretboard diagram to be independent of the bar.

Regardless of what I do, such as click and drag the fretboard diagram up and into a vertical frame, a large gap is created in the score as shown in the attached video (notice Auto-place is off).

Would be great to have this feature in Musescore 4 or at least find a workaround for now.

Thanks for reading!
