I'd like to indicate that string instruments will need to re-bow during a very long note, through a common symbol: A downbow followed immediately by an upbow, appearing over a single note. (I guess string players might find this obvious from the duration of a note, but I'm copying a score, so I need this symbol to appear, because it appears in the original notation.) From the docs, I can see how to put many articulations in a stack on top of one note, but I can't see how they can appear in the same line from left to right. Again, I'd like there to be a downbow mark, followed to its immediate right by an upbow mark, and for these to appear over a single note. Does anyone know how I can do this?
