How do you get your family to join you in running a vet clinic?

Yeah, I know that you get notified, but as I said. It feels like too much micromanaging, say you have a household of 4 sims. All of them working and school at different times. So instead of pausing the game 4 times a day to click on that little lighting and send them to the buisness-lot, a mod would have been amazing.
