Possible Discover University Refresh

I also want to be able to play rotationally without my sims losing their progress. I want to be able to get a household together to move into University and be able to control each one like a family in a normal household. I use to play 8 students in the dorm in Sims2 and I loved the challenge! They would interact with each other, help each other with studies, go out for enjoyment together, some would fall in love and others fight with each other(Usually Angela and Lilith, lol). It was so much fun! I was looking forward to doing that with Sims 4 but you can't. I haven't played much with it because of this. I know I will try again, maybe have students in a home and get them through one at a time and keep them in the house until they all complete college, but it just won't be the same and will take longer than I would like. The best part with Sims 2 was that they all were able to graduate together. It was awesome!
