App Privacy Suggestion

I have the app sharing on so that my son can play games I purchased on my account. The only issue with that is, that if I try and app on my account and I no longer want it, I'm able to remove from my account but not from my son's account. So even if I choose "remove" on his profile, it doesn't disappear.  The only option I have is to turn app sharing off, which I don't want to do. So, I suggest that we would have the ability to choose which apps to give access to and which one don't. That would give us more control over what type of games or apps my kids are playing and a peace of mind.
