Grace notes before-after barlines

I have two players playing simultaneous grace notes. But one must be before the barline (it’s the end of a trill) and the second after the barline (it’s an acciaccatura).
It seems impossible for Dorico. Setting the property for one works for all.
Any solution?
Thank you very much in advance.

The only thing you can do is use the Note Spacing tool in the left panel of Engrave mode. Once you’ve selected one of the little square handles, you’ll need to tab down to (or click on) the circular handles in order to move specific grace-notes separately to their rhythmic position.

Thank you so much.
