Soundfont help

So I downloaded a piano soundfont (Salamander Grand sf2 from https://freepats.zenvoid.org/Piano/acoustic-grand-piano.html - the bottom one) which apparently has one instrument called "Instrument". For solo piano scores it works fine, but it thinks every instrument is a piano when it's on top of the musescore default, and if the default is on top then I have to manually scroll through the entire instrument list and set every single piano part to "Instrument." How can I make it so that for pianos it uses Salamander but for everything else it uses the MuseScore default?
