Linking audio track to a button

I ripped a DVD that only had one audio track. I created a new menu that has addition text for a second audio. I reauthored the movie and placed it back in the original DVD using vobblanker. I then opened the DVD in pgcedit and fixed how many streams there were. I did set the stream attributes too. I also edited the subpic for the highlighted buttons.

Now my issue is, how am I going to link the audiostream to the new button that I made? I was thinking I will probably have to make a dummy pgc and get the button to use that, but I'm not really sure.
