Would you like having part time careers in the game?

I would like to have my wealthier Sims only work one or two days per week. Once they reach max career in some careers they only work three days, but not in all of them. I like having them own/run restaurants or retail stores at that point sometimes, and it can be a bit much if they also have to work 4-5 days, and sometimes kind-of long hours along with the store/restaurant. If we could choose to work part time instead of full time and still advance &/or be at the top-tier of the career, that would be great!
