What do we do if we have a larger family?

Family sharing only allows us to add 6 people. I understand that they don't want us sharing apps with that many people, but I'm more interested in the screen time controls. I don't care about saving money on app purchases. We have 2 adults and 6 children and I need to be able to set up content restrictions and screen time limits for all of them. It feels like apple is telling me, "Sorry, we have no solution for you, how about you switch to android." We can remove 1 adult to add add a 5th child, but I don't know what to do at all for the 6th child, and that puts the burden on 1 parent to do all the screen time management. I'm hoping that you can separate the family app sharing setting from the parental control settings. Keep the 6 limited on the family app sharing while allowing us to be parents to all of our children.
