Adjusting articulations in grace notes

Hey there!
How can I easily adjust articulations in grace notes? By default, Dorico enables an “Articulations” preference panel when I select a generic articulated note, but nothing happens with grace notes.
I have manually moved the dots to position them below the notes, but they are aligned with the stem (in the attached image, look at the first grace notes (badly positioned) and the latest ones—I don’t know why, but Dorico positioned them automatically…)

Thanks!
Albert.
