Rewire Ableton internally with another instance of Ableton

[Chris Deep]

Hi there, i have a quick theoretical question. I have copied my Ableton program map (Mac OSX) so i can open two instances of live at the same time. My question now is: can i rewire these sessions with each other internally? (as in: Ableton master to a Ableton slave on the same computer). I have not yet found a way and suspect that this isn't possible but i'm not sure. If somebody has more info regarding the subject i'd be happy to hear it. The reason i ask this question is because i perform live and it would be a nice project to keep me busy plus i think it would boast an advantage.
Thanks in advance.
Greetings
