How to combine voices in rhythmic unison onto single stems

[beppe]

I am doing a piano reduction from a SATB choral piece. I started copying and pasting all the voices into 4 separate voices.
Is there a procedure to combine the voices as if they were a “block chords” when appropriate?
My first approach would be to move the voices into the same voice and hide the unnecessary rests that will pop up.
In my case I have even a cross staff for the “E” note which probably makes things tricker.

PS: for who is interested this matter is on Gould’s book at pages 472-3

If you use the reduce function, Dorico consolidates music into a single voice if throughout the selection they’re in rhythmic unison. If necessary, copy/reduce in sections to minimise excess voices.

That’s amazing, going in sections makes wonders!
