cannot shift position of voice in polyphony

[Tom Cloyd]

I'm having this problem repeatedly - in several scores

<< \stemDown

{a4\rest \once \override NoteColumn #'force-hshift = #2.0 a gis |} \\

{s4 b,2}

>>

The " \once \override NoteColumn #'force-hshift = #2.0" has NO effect.

I'm using this polyphonic construct to split a voice briefly, in a multi-voice single staff score (classic guitar).

The shift is needed because a note is in a bad position relative to another voice. But I cannot seem to move it. The temporary polyphony construct seems to be the problem, as the override works fine otherwise.

I don't see this problem addressed in the documentation, and haven't yet found a fix.

Any ideas?

[My full, presently incomplete (still entering it) score is here. The snippet above begins at l. 129.]
