Exporting Clips to Media Encoder with Mixed Down Audio

I'm currently doing Dailies for a Movie and have run into a bit of a snag with the Audio that Premiere exports from Media Encoder.

At days end I would select all the clips hit command + m and set up the Media Encoder Queue.

I have an H.264 Preset with the Audio set to Mono.

Problem is that when the clips are encoded only Track One Audio makes it to the H.264.

These Clips have anywhere from 2 to 8 Tracks of Audio and I need a mono mix down of all the Audio Tracks.

Currently I'm exporting the Timelines/Sequences that I use to sync the Audio to the Video (after syncing and slipping the Audio).

The Timeline Audio is set to Mono so I get the desired Audio this way.

Problem is the extra time it takes to not only name the Merged Clips but then the Timelines as Scene/Take as well.

I also end up with extra Bins and a ton of Timelines that I no longer require after the clips are Merged and the potential for Typos.

Is there a way to send the Merged Clips not the Timelines/Sequences to Media Encoder with a Mix Down of all the Audio Tracks.

Thanks
