I currently use the G500 but I'm thinking about swapping to the G400 and I just want to know if you can assign left and right scroll to a button/number/etc as I really need those extra binds for certain games.
The setpoint software is the same so you should be able to assign any button to do anything you want.
I have the G500 and I can assign the left/right scroll to a plethora of keys/numbers/etc. Are you sure you have the right version of SetPoint?
