Help with musescore 4 dynamics

Hey everyone, I'm not sure if this is the right place to be asking for help, but I don't know where else to go so here I am. In Musescore 3 there's a feature with the inspector where you can make a dynamic marking only apply to a specific staff, while not affecting the other staff for the same part. This is something I use a lot for composing piano music, but I can't figure out how to do it in Musescore 4. Does anyone know how to do this? Or is it a feature that's still in the works?
