Need help making a custom score for drum group.

Hello!

I'm new to musescore and notating in general. I'm planning to make drumming tracks for someone who teaches beginner drummers. They need it notated.
I need help setting up the program so I can import the MIDI file into the following format.

Hi Perc 1 D#4
Hi Perc 2 D4
Hi Perc 3 C#4
Hi Perc 4 C4

Mid Tom/Perc 1 D#3
Mid Tom/Perc 2 D3
Mid Tom/Perc 3 C#3
Mid Tom/Perc 4 C3

Low Tom 1 D#2
Low Tom 2 D2
Low Tom 3 C#2
Low Tom 4 C2

I have tried adding an instrument group by editing the intruments.xml and having them show up in the program by following the tutorial found here, but it said unpitched percussion will have different syntaxes. I couldn't find the right syntax for unpitched percussions.

I have also tried making a soundfont using Polyphone and using them with Sforzando in the program.
