I am a little unclear of what you are trying to accomplish.
""Is it possible to have whatever button is highlighted to continue to be highlighted when the menu starts over at the begining of the loop?""
""Currently whatever button is highlighted is set to the menu default when the loop action occurs""
You are asking, I believe, if the default highlight button can be left highlighted while the motion menu loops but currently the highlighted button is set to default?
HUH????
The purpose of the default highlight for the, lets say PLAY button on the main menu is to allow you to click it at any time to jump to the main track(s). You might then return to that main menu when finished playing the main track(s) and the default button should still be highlighted.
