notes with two stems (one up and one down)
A commonly used device in 19th C. 5-string banjo notation is to place an upwards flag on notes played open on the 5th string (G, in modern gCGBD tunings). This is actually a fingering guide as that note may also be stopped on the 1st string, 5th fret (again, in typical modern tuning) or elsewhere on the fretboard.
At the moment, I'm entering my notation into musescore normally and then creating a 2nd voice to add this flag to notes where I desire the flag to occur. This is a labor intensive process...esp. if I have a larger score with potentially hundreds of "open G" flags to insert. It also creates issues in that the second voice is a 'fake'. When I cut/paste the notation into tablature, I get two notes in the tab staff...and some squirrely beaming.
I've learned to create notation as basic, cut/paste to the tab staff and then add the flags to the notation staff afterwards. Linking the two staffs simply creates more issues than its worth.
Is there a shortcut (or better mousetrap) to achieve that double stem on a given note? Using voice 2 fills the staff with rests (if the note is other than the first beat) that have to be deleted, etc.
