Cue-sized notes in ossias mis-aligned

Is it possible to adjust ossia note horizontal alignment?

I’m finding that cue-sized notes on ossia staves are ever so slightly mis-aligned with the full sized notes on the main staff. Or perhaps they’re just left-aligned, and I’d like to center-align them.

Dorico’s alignment is correct, insofar as that it’s correct for the left-hand sides of these notes to be aligned (the left-hand side of the front note determines that start of the rhythmic position). If you want to adjust this, you’ll need to do so manually in Engrave mode using the note spacing tool: select the square handles for each of the notes in the ossia in turn, then hit Tab to go to its round handle, and nudge that right with Alt+right arrow.
