Independant staff size per flow?

Hi,

I have a mega project with about 45 flows. The Full scores are on A3 and parts on A4. There are a few flows where everyone plays where Id like to have a smaller staff size, in the Full score, than in the other flows. Is this possible?

Many thanks

Yep. Enter a system break or a frame break wherever you want to change the staff size, then select it and play with the properties panel like so:

Dorico will automatically reset it at the start of the next flow, but you can change it as often as you like manually, at the start of any system or frame.

Excellent, Thanks much!!
