Sims 4 eye customizability without mods

The sims 4 needs heterochromia as a customizability option for the sims' eyes, it has been highly requested and would be huge for people who love creating their sims  

It would be very quality of life and add more much needed customization for unmodified base game sims, this would be very good for people who can't or don't use mods in their game and it would be very easy for players to get used to if it was added as a simple toggle like how it is for the sims 4 cats and dogs, it would be a simple way to add more representation and be appreciated by players

Thank you!
