Unis. text placement in score

Hello all,

I ran into a hic about the unis. text placement in the score, in the strings.

I have used the method to go back to unis. immediately after the divisi,
(galley view) :

to let dorico the possibility to go back to single staff system as much as possible in the part.
and what have understand this is the way to do it (?) : where should the unisono text appear? - #3 by dspreadbury

But then I run into these situations in the score, where the unis. text is where the signpost is - just after the divisi section.
I need the unis. text on the first note of the unis. section…

but if I go back to unis at the unis section start, in the part I’ll have a series of empty measures on a two staves system..

And another thing is that if I want to put the unis text following the unis signpost on the start of the unis notes (in score) :

like this (in score) :

I end up with this in the part - with a missing rest that I’m not able to put back.. :

instead of (in the part) :

It seems that I’ have problems either in the score or in the part..

Also, since I’m in a condensed score I can’t even put a manuel text “unis.” and hide the first “unis.”…
How to do this ?
I’m certainly missing something..

Sincerely,

Joakim
