Brackets in piano score
I've come across some brackets that span both staves in my Open Score transcription of Kosenko's 11 Etudes that I can't quite figure out how to replicate in Musescore. You can see what I'm talking about on the first and second lines of the second page of the PDF. I've approximated them with symbols that I found in the master palette, but I don't know if they're the correct ones. I can't seem to find any symbol that replicates them exactly.
