Selecting a radio button with event listener on Button symbol

Since I have been unable to find methods of styling the radio button components in Animate cc I want to select a radio button by putting a Click event listener on another Button instance.

Presumably create the radio button on stage and hidden, or possible better, include a form with radio inputs on my .html file outside of the canvas div and have the display:none. Is this possible?

I have the Event listener from the Code Snippets on my button:

this.yes_button.addEventListener("click", fl_MouseClickHandler.bind(this));

function fl_MouseClickHandler()

{

// Not sure what to put here to select radio button.

}

All help is appreciated. Thank You.
