Audio editing room
There should be an audio editing room where you can record audio and make your own soundfont.
You can actually get the audio from your score and edit it with audio mixing tools and make crescendos and diminuendos on whole notes and other stuff, plus you can make the sound louder or quieter and there is a lot more you can do in musescore with an audio editing room.

That's why DAW software exists. MuseScore isn't a DAW, it's a notation/engraving program.
That being stated you'll be pleased to learn that single note cresc/dim will be supported by the next major release.
