Show Value of Points in Rewards History

On the cart and checkout pages the plugin shows not only the amount of points a user has, but also the value of these points (depending on the currency applicable to the order).

I would like this to also be the case when the rewards points history shortcode is used. Right now it only shows the number of points a user has, and not what the value of these points are. I would like it say something like ‘You have x points, which are worth a discount of x amount’.
