Reply to JogWheel mapping - scratch button

I use traktor dj with a Mccrypt me-100 controller. I have mapped the jogwheel for Tempobending and seeking when deck stopped.
Now i want to make it scratchable /although jogs arent really someting you would expect to scratch with/.
I have a scratch button - I want to turn the button on and then be able to scratch. And when i turn it off jog acts normal again. How do i do it?
"jog turn" and "jot touch on" is only for the jogwheel? The jogs arent touch sensitive.
