Dear pianoleo,
thank you for your answer. I just found the option (cf. my next-to-last post). It works perfect - but as I already mentioned, it takes much time and many mouse-clicks and keyboard-inputs. It feels as if Dorico’s basic idea of avoiding sophisticated workarounds (like in other apps) turns back into a still more sophisticated brain cramp when things are a bit unusual. Sometimes it feels like a graphic version of lilypond … But may be I got this feeling only because I’m very very new to Dorico.
Thanks a lot for your help!
Ben
