how to combine two mono tracks into one stereo track?

I've got two mono tracks panned left and right.  I want to convert them into one stereo track.  I'm sure it's easy to do - but It's really got me puzzled.  I don't want to re-record it to a stereo track - I know I could do that faster than it took me to ask this question - but I'd like to learn how to do it with a quick command.
 
Oh ... I suppose I could just highlight the two tracks and export them to a stereo wav and then import the wav back in.  That's pretty easy but I'm still curious if there isn't a way to simply grab the two tracks and tell Sonar to combine them into a stereo track?
 
Many thanks in advance

Thanks CJ ----  I shoulda thought of that.
 
thanks again.

CJ,

I'm using Sonar 8.5 PDR.

I select two tracks, and use Edit / Bounce To Track  (There isn't a menu choice for Edit / Bounce / Stereo - either Edit / Bounce To Track or Edit / Bounce To Clip). The two mono tracks are panned hard left and right, respectively.

From the Bounce To Track dialog, I select Destination New Track, Source Category New Track, Channel Format Stereo. The option boxes are all checked (default).

I end up with TWO new stereo tracks - one has the left channel with audio and the right channel silent, the other has the right channel and the left channel silent.

What did I do wrong? I want to end up with ONE stereo track containing the two mono tracks audio, one on each channel.

Thanks!
