Left bar lines
Is there a way to NOT display a left bar line between the bottom of the first bass staff (lower staff of the grand staff) and the next (bass) staff? See attached MS file. If I change this in Styles, I lose the left bar line for the grand staff altogether, which I don't want. If I hide it, it does something wonky (see attached image). Or is there a way to manually add a left bar line for the grand staff, but NOT the single staff instrument below it?
