aligning melisma and non-melisma lyrics across staves in the same system

[Kieren MacMillan]

Hello all,

I know there is a way to have accidentals “cross-canceled” between staves in 
the same system.
(I’ve used it… and it’s wonderful!)

Would it be similarly possible to have lyrics aligned between staves when one 
or more of the lyrics is melisma-attached (and is thus automatically 
left-aligned, according to the value of lyricMelismaAlignment) and one or more 
lyrics is not (and is thus centred, generally)?

Thanks,
Kieren.
