Hyphen instead of chord symbol when the same chord is repeated with different bass notes using slashes

Apologies in advance if this question has already been asked. I searched to the best of my ability, but
I'm working on a chord chart for a fellow piano player (please see attachments):

I'd prefer if it was possible to write the chord symbols as follows, as it would make the chart considerably more legible:

| G5 -/Bb -/C | G5/F -/A -/Bb | et cetera

I've tried writing with slashes anyway, but in that case the bass note symbols are not interpreted by Musescore and therefore not rendered correctly (note the difference for b-flat)

Ideally, the bass note symbols should use a smaller font, but even without legibility would be improved.
Is this possibly in musescore 4.5.1 or is it in the pipeline, perhaps?

I'm also wondering if there is a way to move the chord symbols horizontally, so the center - instead of the beginning - of each lines up with the note it's attached to? Selecting all chord symbols, using the filter and dragging with mouse only partly works, because shorter symbols gets shifted too far left.
