When scoring for music theatre, I would find it useful if Dorico allowed me to either suppress playback of certain repeat marks, or (more logically, I guess) set “play n times” to 1. Currently, it can’t be set lower than 2 – which makes sense, except for “Safety” bars that aren’t actually intended to be repeated unless something unexpected happens, such as a singer missing their cue.
You could stop repeats playing altogether by setting the option in Playback options>repeats
That’s nice, but would only help in scores without actual repeats.
