Musescore 4 - Allocating different dynamics to different staves within an instrument

I'm currently writing for pipe organ and I am aware that there are different manuals, registrations and boxes that can control the dynamics of individual manuals. I would like to ask if there is anyway to isolate each dynamic markings to the individual staves? I could do it in Musescore3 by changing the settings for the marking to be staff specific but I can't find the same settings in Musescore4. Thanks
