Adding the Pan function to a mouse button

I have a Logitech mouse that uses SetPoint. I would like the sideways function of my wheel to function as Pan. In Acads CUI there is a list of ten buttons which different functions. How do I know which button is which? None of them have Pan by default, so how can I add it to a spesific button?

Try using X-Mouse Button Control.

I never cared much for Setpoint.
