Rookie Programmers-Mecanum Help Wanted

[Team3220]

We are first time programmers, and we have decided to go with a mecanum drive this year. We have been running the default roboRIO Mecanum With Arm code, and we are driving great. However, our driver hates using the z axis (the little dial) for rotating. How would we change it to buttons 4 and 5 on a Logitech Attack 3? It's the default code, but we can post a picture if you guys think it will help. Thanks!
