Can audio be separated into two channel tracks once it’s already on the timeline?

I’ve recently upgraded from my ancient Premiere 6.5 to CS6. I’ve got 4 hours of edited footage that is showing myu audio only in  the Audio track #1. I am not seeing each channel separately. I need to edit the audio channels separately.

 

I just discovered that I should have changed an audio setting for each clip prior to adding it to the timeline in order to have the audio channels display separately.

 

Can audio be separated into two channel tracks once it’s already on the timeline???? I sure hope so. It could be done in the old Premiere prior to Pro.

 

Please help. I am anxiously awaiting a response. I’m on a tight deadline.

 

Thank in advance to anyone who can respond.
