Sony Movie Studio 12

Hello. I'm trying to render a video in Sony Movie Studio 12. I already edited the video and the audio is 5.1, so I have 4 audio tracks. When I render the video as a 480p Mpeg2, it only gives me the option to have stereo sound. When I rendered the video, it didn't have all of the sound. Just one audio track was present on the finished movie. My source videos are 480p, so I want to leave it the same. Does anyone know if there is a way I can merge the 4 audio tracks into 1 audio track (so I can just use stereo sound) without having to go back through and re-edit the entire thing. You can begin the project with just 1 audio track if you choose stereo from the start of the project. This is a 10 hour movie and it took a long time to edit it. I will be using Multiavchd to burn this onto one Blu-ray disc. Is there a way I could render the movie as 1 video file and 1 audio file and then combine both onto the Blu-ray disc?

I figured it out.
