Change of attack time and note duration in Musescore 4?

Hello,

I was wondering, if there is a workaround in Musescore 4 to manually change note attack time and duration? In Musescore 3 it could be done by the Pianoroll Editor, which is not implemented in Musescore 4. It was very convenient because you could manually set appoggiatura before the beat and the main note on the beat. Is there a feature I'm missing or is it planned to implement in the future?

Thanks
