Individual spacer should automatically, immediately fill space between staves.

At the moment. when I add the "Downward" spacer, a very short spacer appears. It takes me 12 times ctrl/down arrow just to get to the point where it begins to make a difference.

I think it should immediately join the 2 staves, eliminating the initial 12 strokes.
