Extending lyric extender

[Yann]

Hello everybody !

I have the following situation in few hymns (SATB) I'm typesetting :

I chose to use the lyrics extender when for example, choir singers have to hold a long note on a phrase ending, especially when, for example, one voice sings a half note while some others sing 2 quarter notes.

I thus use the extender to remind all singers to hold their note till the end, else the voices singing the two quarters will be heard alone.

In my generic setup, I'm attaching the lyrics to the soprano voice.

Everything is fine when the soprano have the 2 quarters.

But when the soprano sings the half, and alto sings the 2 quarters, then the extender is too short.

It is only slightly wider than the half note, instead of being as wide as the 2 quarter notes of the alto voice.

Is this behaviour normal ?

If so, is there a way to "extend the extender" so it takes the full duration of the half note ?

I'm not sure everything is well explained, if needed I'll try to make a minimal example.

Thanks !

Yann
