Different Flow settings

This may be very basic, but I can’t seem to find the answer in the docs or videos.

I have a file with three Flows. I would like to have the instrument name appear on the first Flow/Mvt, but not the following ones. It appears that a Layout Option applies to all Flows in file, while Notation Options can be Flow-specific. Likewise, is Staff Spacing/Justification a a file-specific setting, or can it be flow-specific?

(I figure out how to turn off barlines for the second Flow - that was needed as it is unmeasured, whilst the first and third are barred.)

Thanks in advance. Really starting enjoy using Dorico!
