Set Business Hours - Auto Open & Close Vets, Retail, Restaurant, etc

I agree the same with small businesses now, I have a business hire one of my current sims but i want him to have actual work hours not just whenever i click open. because that means so many loading screens. I just need a consistent time and I want it to be at the nightclub as a band so that he can get tips too, and get fame raise not just a wage.
