Verical spacing of staves Q?

Trying to find a way to expand the spacing of staves in the middle of a frame. Somewhat like we can do with a few measures in a stave. Expand the selected items wich are selected while other compress.

You can’t do this in a single motion, but you can use Alt+drag on the handle corresponding to the top staff below which you want the spaces to be compressed, as that will scale the distances between staves proportionally, and then you can use regular dragging to make the distances between the staves above larger. You can also type a measurement into the ruler control in the left margin.
