Multiple Audio Setting Selection In PMHD

I've been using the PM3.HD skin on my Xbox for a while now, and I'm quite pleased with it. However, one thing is holding me back from using it full-time; audio selection. The MC360 skin allows me to select which audio track I want to use for a video, while the video is playing, no less. But the PM3.HD skin doesn't even let you change audio options ANYWHERE! Is there some hidden menu that I need to access? Anybody who watches anime knows that switching between audio tracks of a video file is a necessary feature, and if PM3.HD does in fact support it, that would be fantastic. So, how do I access multiple audio track settings for videos in PM3.HD?

I'm probably a bit late replying on this but its in the same place
