@Toaster1974 This solution works in Sibelius (I tried it just now), but in Dorico, Galley view only applies to Write mode, and in Write mode, dragging the line changes the number of bars in the ending such that the second ending bracket moves as well, which I don’t want.
@Lillie_Harris I don’t want to change which bars are played in the ending, only the length of the line (see the last line of my post).
The first screen grab shows the 1st ending line as originally entered as it appears in Engrave mode. Each system has 4 bars (sorry for the ugly redaction graphics!). This single line has four segments, the first three in blue, and the last in orange because it’s selected.
The second screen grab shows what happens when I grab the end of the 4th segment and drag it to the left. I can shorten it a little further, until it’s just a vertical line. Similarly, I can take the 2d and 3d segments and drag them to the left until they’re just dots.
But what I want to do is to shorten the line so that instead of covering 16 bars, it covers only 4 bars, without changing the location of the end-repeat bar line or the 2d ending line.
Unless I missed something, nothing in the Properties menu will do this.
Since Dorico allows me to shorten the ending line appearance, I don’t see any reason it should be limited to one system.
I found a work-around: by selecting a line segment and clicking in the middle of it, I can drag it off the page in Engrave mode. Back in Write mode, the line length is unchanged, both in Galley and Page views. This gets me the result I want, as in the third screen grab.
The problem here is that if I ever change my mind and want the line to appear as originally entered, I can’t access those off-screen elements; I’d have to delete and re-enter the ending.
