Sims 4 Add Preteens Life Stage

Don't get me wrong, I love the Sims 4. It's a fun and interactive game. But, for me there's a missing piece. There is an awkward space between kids and teens. The game just skips over preteens. There's no middle school, no growing between the two stages, which look to be going from 8-9 to 15-16. Middle school is a tough time, and I played The Sims games when I was that age. It was a nice break from all the awkwardness, but I also felt under-represented as my age. I couldn't make a Sim self and neither could my friends. It would have been fun for our Sims to grow along with us, and for all those awkward things to happen to them too. Sims were my safe haven. I wanted them to have crushes, go to middle school and, yes,  have body changes like I did, and so many people who play the Sims 4 do. I know this has already been suggested before, but it holds a special place in my heart. The mods and cc that are available aren't good enough! So please take this into consideration!
