Traktor & Ableton on Apc40 - Help Please

Please help.

I am currently running Traktor and have synced Ableton Live running this in my Xone 4d.

What I really want to do (getting a Apc40) is continue to use this set up but run it on the Apc40.

Hence half of the Apc40 running Traktor and the other half of Ableton on the Apc40.

As Im a newbee to Ableton, I can see u can add a limiter to master track.
Q) Is this possible to add a Limiter under the setup above that I wish for .

Someone out there must be doing this surely.

Help really appreciated.
