Play Controller side buttons

Hi, the side buttons on the Play Controller are not used outside of a workout. Would it be possible to integrate them with the leaderboard on the left hand side of the screen.

For example, when I am riding I am often shown an incorrect leaderboard for a segment that it believes is ahead. You can switch between these using a mouse and clicking on the buttons at the bottom, to get to the right segment. However, using the controller could allow them to be tabbed through to get to the right one.

Would it be possible to programme the side buttons of the Play controller to control this leaderboard section when outside of a workout?
