Getting Logic master to send to both 1-2 and 3-4 at the same time

Question

I have an native Instruments Audio Kontrol 1 'sound card' that I'm running 2 different sets of M-Audio monitors off of. My question i, can I run the master output to both 1-2 and 3-4 at the same time so I can easily check mixes on both sets of speakers without changing every single tracks output?
Also, is this possible to do in iTunes also? I can find nothing in Logic (or anywhere) that will allow this and I initially thought my device was broken until I simply choose 3-4instead of 1-2.
thanks so much!

In Logic you could just setup additional sends of your Audio tracks using the send knobs and send the signal to a Bus. Set the outputs of that Bus to 3-4 and you'll have your signal played through 1-2 as well as 3-4.
Also, if any of the audio tracks used sends (reverb on a bus..etc) those would also have to be sent to the same bus as the audio tracks.

How about routing all the outputs that are currently on Output 1-2 to a bus first then:
Option 1: Switching that bus's output between outputs 1-2 and 3-4 (for A/B comparisons)
or
Option 2: Use the Send on that bus's output to another bus, route that second bus's output to 3-4 (so both busses are sending audio to both sets of speakers simultaneously).
As an alternative, the Mackie Big Knob is a great hardware solution for routing a signal to 3 sets of speakers, allowing you to switch among them with simple button presses.
