It just so happens I set a hymn this weekend. I used two generic “voice” instruments in my score. I put S in first, added a down stem voice to input A; I repeated this process for T&B after changing the second line to bass clef. The whole process took me a matter of minutes. Drop in my text and it was all said and done rather quickly, all opposing stems, looking just the way it was supposed to. (NB: I found using two “voice” instruments better as the barline does not extend through where your verse text should go but they are still bracketed together at the beginning of each line. I did it in a piano grand staff first but ended up copying and pasting the music into the vocal lines that I added after the fact and then I deleted the piano.)
