Re: Is there a better way to have a boxed part letter at the beginning of an arbitrary line?

[Kevin Cole]

P.S. Ideally, I want to make it part of a template, and be able to
quickly replace the notes in the first measure of each part without
having the part letter markup "embedded" in the measure between the
first and second notes. I'm hoping for a way to specify it so that it
is not tied to a note, but tied to the beginning of a line.
