Apend text to loyalty coupons

When redeeming points for a free product, customers see the automatically generated coupon code in their cart and at checkout.  This can be confusing for some customers. It would be great if specific text could be added to each code which would identify the code as being related to a loyalty redemption product eg “Loyalty Redemption - XXXXXX” .  Then customers would be able to identify that the random coupon code they see is associated with the product they have redeemed.
