Tremolo and 3 dynamics (Musescore 4) on Timpani (3 beats/tacts)

I find tremolo and dynamics on full note in Timpani.

How to create that.

Full note (tremolo 32)
Fortissimo, subito piano, crescendo < in one beat/tact

How to make all that, because when I've tried crescendo going to next beat, or going between ff and sub. p
