Flow Indication in Parts

In a 3 mvt (3 flow) piece I am writing, I looked at the timpani part so I would have an overview of the notes and tuning changes needed. I was quite surprised that there was no indication where one flow ended and another started. That seems very odd to me.

Maybe you have set this in Layout Options of the timpani layout

@TonH Thank you very much. I work in Dorico several hours every day, but I have not really focused enough on learning layouts.
