I'm wondering if I just missed it or if there is an equivalent in Sibelius 6 to the mirror tool in Finale -- I have a bunch of measures that are repeated at various times throughout a piece. In Finale, I would just say these measures are mirrors of the original measure and then I wouldn't have to edit them.
I realize of course that I can just create the original measures and copy them -- but the point about the mirror tool is that if the original measure is edited, the mirrored (copied) measure is also changed.
