Transfer platforms!

Hi I’ve been playing sims since the very first one dropped! I really want to throw my 2cents in the community. I feel as if we should be able to crossover our packs through different platforms because I done bought just about every pack on her except the last to expansion packs and I just bought a ps5 thinking I’ll be able to switch my games on here instead of using my slow computers. Can yall please find a way to make that happen? Even if it’s discounted I just really don’t want to spend all that money again. Seriously who would I have to talk with about this?
