Messa di voce with dynamic

When I write a Messa di voce with an initial dynamic sign (see picture) the cresc. part of the messa di voce will be shortened. I would prefer, when both parts of the messa di voce would keep the same length and both parts would be shortened by the same amount.

So far I didn’t find a way to change the middle position? Did I miss something?

Have you tried inputting the hairpins one e.g. 1/32 note later than the piano sign? Maybe this works.

Found a place to adjust the center: “Messa-di-voce-Tonfall”.

Hallo HeiPet

Wurde die Transposition vom Tenorhorn im Violinschlüssel in Dorico 2 korrigiert?
Danke.
