How can I move the coda symbol above the bar lines

Basically, I'm writing a leadsheet, and I want to position the coda symbol exactly above one of the bar lines. Because of the way my piece is set up, "/repeat segno" doesn't seem to work, so I'm simply using "/coda" instead. But, as far as I'm aware, this automatically positions the coda symbol above a note, not the bar line, and using "/offset" also offsets the bar line.

Has anyone experienced this before? I'm still a novice, so it's possible a simple solution exists, but I've tried everything I can think of and everything I've seen in the manual, yet nothing seems to work...
