Quality of Life Improvement: Rod Of Ages

There are three items with the unique passive, Eternity; Rod of Ages, Abyssal Mask, and Catalyst of Aeons. Every time a champion equipped with these items takes damage, they gain mana and they can spend that mana to regain health. I was wondering if it was possible to implement a quality of life improvement where the unique passive has a tracker. It would be nice to have a little text box on these items that displays the total amount of mp and hp gained from Eternity. It isn't much, but I believe it would help users see how effective the passive is, or how effective it isn't. I would like just a simple change to the item with an added text box tracking the amount of healing and resource regeneration it offers. Thank you for reading and please put your thoughts below!
