WooCommerce Points and Rewards

Make it possible to set a global maximum points earned for each transaction. In other words, when a customer makes a purchase, set a global limit to how many points they can earn for that transaction. For example: If I have my points to dollars ratio set to 1 point for each $1 spent, and my customer makes a purchase for $800, I would like their points earned to be a maximum of 500 points.
