reassignin buttons on logitech mouse Anywhere MX

[Poedel]

it one of the latest mice produced by logitech. With my "stationary" Laptop I am using MX Revolution. There I used revoco to reassign the buttons.
This is not capable of the new Anywhere MX. Even lomoco does not support it.
Probably some sourcecode tweaking might help. But C & is not quite my language *G*.
What it does in default way:
Pushing the wheel turns from free spinning the wheel to stepped spinning & vice versa.
There is a little button behind it that is used as middle mouse button. Really unusual I suppose.
My Revolution switches the spinning methods by pressing the little button an keeps wheelpushing treated as middle button action.
That's what my new mouse should do, too.
Any help is welcome
