diagonal lines between RH and LH staves in piano music
I'm transcribing a number of songs with piano accompaniment that use diagonal lines between the RH and LH staves to indicate when a voice moves from one hand to the other. For example:
Is there a standard way to do this in MuseScore? I've tried a couple of different items from the "Lines" menu (e.g. "let ring" and "palm mute"), and while I can get the look I want by turning off "automatic placement" and turning on "allow diagonal", it doesn't last. When I close and reopen the file I discover that these lines have been restored to their default state ("automatic placement" on and "allow diagonal" off). That means that any time I edit one of these files to make any kind of correction, I have to go back and fix the placement of these lines before I can print the file out.
Any advice would be appreciated.
