Dorico Spacing Leaves Large Spaces Between Some Systems

Is there a way to select staves and drag them so they all resize together retaining their distance ratios? I am able to reize each staff individually, either by dragging or entering a value, but not a selection.

I’m working with a piano/vocal score and set the rastral to size 7 which gives a reasonable appearance. However, some pages have large distances between the staves which I would like to equal out somewhat.

I understand that Dorico has applied various calculations for spacing and this is excellent although this has resulted in large spaces betwen systems on some pages.

Thanks for any help with this.

You can concertina drag staves up, but not down. In Staff spacing mode, hold down the Alt/Opt key and then drag the lowest handle upwards with your mouse.
You might also try playing with the settings at Layout Options > Vertical Spacing > Vertical Justification.

Thanks Pianoleo.
