I’ve attached a scan of a pencil score I’m setting in Dorico. This is one measure of a harp part. I set it with all the notes in one voice and then marked all the lower notes shown and dropped them to the lower staff with M. So far so good. Usually the purpose of that is to put the beam in the middle, i.e. between staves.
However, is there a way to make the entire thing upstem as shown in the original? I wouldn’t normally do that, but there is an aesthetic reason to want that in this bar. I can flatten and raise or lower the beams in Engrave Mode, but I’d like to see it all upstem in this one instance. How can I do that?
