Bach Crab Canon special effect

Dear Dorico,

Is it possible to achieve the original layout that Bach used for his Crab Canon? It is a mirror-like effect, I post a link for reference.

You can’t currently rotate symbols directly in Dorico, but you could certainly create SVGs of the clefs and accidentals needed for the upside-down clef and key signature at the “end” of the piece in another application like Illustrator, Affinity Designer or Inkscape, and then position them as custom playing techniques in Engrave mode.

Here’s a Dorico version of Quaerendo invenietis, with an upside-down bass clef, if that’s useful.

Thank you Stephen! It is nice to find some some work already done!
