satb and pianoreduction

[Orm Finnendahl]

Hi,

following the example given in the docs I typeset a 4 voice piece with
automatic transcription of the 4 voices in a piano
staff. Unfortunately the piece starts in the soprano with a stem-down
note (the other voices resting). In the piano reduction, this voice
retains the stem direction although it would be preferable if the
soprano *always* has a stem up in the piano staff. In addition the
rest in the alto voice is missing in the reduction. In Bar 3 of the
piano reduction there is a similar problem in the alto voice, where
the stem direction is up instead of down,

Is there any way to define a fixed direction in the stem for the
individual voices of the piano reduction without having to duplicate
the source material?

The source is attached.
