Admittedly, it’s rather bizarre request.
Here’s the way - conventional and reasonable - that Dorico renders seconds.
Yet, for some specific reason, I’d like to have the note-heads in each double stop to be placed in opposite horizontal order - i.e. the top note to be placed to the left of the stem and the bottom (crosshead) to the right of the stem.
Is there a way to achieve that?
On a side note: as it’s seen in the screenshot, the double-stops aren’t grouped evenly. Curiously, if I force the stems to be uniformly ‘up’, the spacing is rendered perfectly even.
