Railworks America

So I'm finishing up a few loose ends and I am completely lost at this point. My question is, what exactly am I supposed to reference in the following areas located in the main blueprint?

Bogie audio control name
Coupler audio control name

After studying other cars I added the following for the bogie:

Kuju\RailSimulatorUS\Audio\RailNetwork\Bogies\BG_Modern

Anytime I try to export I get a 'file not found'. I added a wagon sound child and I have it aliased to

Audio\RailVehicles\Wagons\Wagon Freight Sound.xml

Anyway, that part works fine. I just lack coupling audio. It looks like this is my final hurdle. Any help would be greatly appreciated!!

Any ideas at all? I am assuming this is directly related to my lack of coupling sound on my rolling stock. I've included a screenie to clarify what I'm looking for.

Problem solved. Manually edited the bin and added the lines. Worked like a charm!
