Thanks Daniel. Yes, I have reviewed all those options and tweaked them according to my preferences but it doesn’t help me with ties and groupings within a single beat at the moment.It is indeed a bigger problem under tuplets. I can see how allowing flexible grouping for every situation could become very complex. Perhaps a simple Preferences checkbox for preferring dots to ties might be a simpler solution. Of course I have no insight into the way this is actually programmed in Dorico so forgive me if that is a little presumptuous. Best, Michael
