More Trait Slots With Each Expansion

I have always found it silly that with all these expansions and additional traits we get, we don't also get additional trait slots in cas. With each expansion purchase we should also receive an additional trait slot, after all we are paying $$$ for them and want to actually be able to use all these traits. It doesn't make sense that owning all the DLC means I still can only start with the same number of traits as I can with just base game. It makes no sense to me. Especially since so many packs focus on giving our sims more personalities. Let us actually optimize these features!!! I know we can cheat add traits but it is an exhausting process, especially if you are like me and obsessively spend too many hours making each background character far more detailed than you need to. I beg for a future update that allows this. It works great for just base game, but we really need more trait slots for additional packs!!! PLEEAAASSSEEE!!!!!!!!!!
