Slur across staves and line ending
I'm working on a piece of music in which the harmonic line moves from the tenor voice to the alto voice, calling for a slur from the tenor note (in the bass clef) to the alto note (in the treble clef, in the next measure). But as it happens, a line ending intervenes between the notes, at the measure break. So the partial slur needs to be in the Above position extending from the tenor note before the line ending, but in the Below position coming into the alto note after it. It appears this is not possible.
Any insight on this?
