Midi Devices panel CC question

I’m trying to recreate certain buttons from my Nord Lead 4 on a midi device panel, and i’m having a hard time getting it to work.

The Unison button has 4 modes. no unison, 1,2 and 3.
Everytime i press the button it goes the next. Each has his CC value, 0, 43, 85, 127.

If i create a button (one shot) it adds the value +1. So i need to press it 43 times in order to get the same result. Is there a way i can add these values so everytime i press the button it skips to the next 0>43>85>127>0 etc?
