Can I listen to a 3-track recording in Waveform mode?

Right clicking on my 'numbers' only seem to let me rename the box, it doesn't alter what I can hear. Selecting my number 1 the box to read 'right' still comes out of the number 1 channel.

Thanks for the suggestions. I can't get the "L" and "R" boxes on the right to work on my CS6 version. Very strange. I would have thought that with all the complex routing and assigning available in Audition that it could do this simple job.

But I do have the solution: that good ole reliable audio workhorse that is always in my Dock just in case: Audacity!

I knew there would be a better way but where do you find the boxes that say left and right. It might be because I have a multi channel interface but this is what I have.

There's a way to hear all three, but the third one has to be in either the left or right channel - you can't pan it to the centre. At the RH end of the waveform display there are boxes that say L and R. If you right-click on the one you can't hear, then you can select either R or L. I haven't tried what Richard is suggesting; that may improve things, but I suspect it won't, because there's still no panning option available for the track. In a multi-channel interface it would work, but not in a stereo one.

This is not the most elegant solution but I can hear the three tracks played through a 2 channel audio device using the following setup:
