Assigning Different MIDI Channel to Bass Clef

I think the title explains my situation. I play the Yamaha Clavinova piano, and I can import midi files into the smart piano app to be able to learn songs much more easily than just reading the sheet. However, when I import regular midi files, the bass and treble clefs end up being mixed together and it's hard to read whenever I want to actually look at the sheet instead of the stream lights. I accessed the song I wanted to play within musescore 3, but whenever I tried to change the midi channel, it would change the channel of both the treble and bass clefs. Is there any workaround for this?
