More Lifespan Options

I get bored too easily with the sims 4 and I realised it's because of normal lifespan being far too long for me, particularly the teenage years.

I've been playing on short lifespan and really enjoying the struggles, but the elders don't get long enough.

I have lost count of the times I have tried Not So Berry challenge and given up because everything gets completed too quickly and I just want to move on to the next generation. However , by playing on short lifespan, I'm proud to say I am on the 9th generation and only used the potion of youth twice and limited myself to only using it on elders.

I would love sliders for the sims 4 lifespans like the sims 3 have, or a few more options in settings.
