Keeping Button Highlighted

Hi. I'm trying to build a setup menu with DVDSP that keeps selected options (5.1/stereo, subtitles, etc.) highlighted but I can't seem to wrap my head around it.

For example, I have a "setup menu" that has a "audio options" button that goes to the "audio sub menu" that has 3 buttons, "setup" which takes you back to the "setup menu," "5.1" which selects the stream with 5.1, and "stereo" which selects the stream with the stereo track.

When I click on the audio options button I want the audio sub menu to appear with the stereo button highlighted to indicate that stream is selected. If you select the 5.1 button I want the highlight to move from the stereo to the 5.1 button. Then, if you navigate down to the setup button the 5.1 should still be highlighted and if you select the setup button, go to the setup menu, click the audio options button to take you back to the 5.1/stereo menu, I want the 5.1 button to still be highlighted.

Basically, is there a way to script something that tells DVDSP to remember what options/buttons have been highlighted?
