We need a better genetics system!!!!

As the title says, we need a better genetics system. As someone who likes to play legacy gameplay, I like to go into CAS when the kids age to see how similar they look to their parents. I wish they had implemented the sims 2 genetics system into Sims sims 4. I can't tell you how aggravating it is for me to have to go back to CAS and edit them to make them at least look somewhat similar to their parents or even go as far as having to download mods. I'm not sure if they'll take this into account or if even people really care about stuff like this, but I would just like to hope that this will change in the near future.
