User Code for User Profiles on Apple TV Device

My family of four decided to start using the user profiles feature of Apple TV. However, when using Apple TV, there is no indication of what profile you are using unless you consistently use the Home button to look at the profiles. What's worse, why is there no access code for each profile? For example, my kids may want to watch something so they turn on the TV go straight to a show. They don't check to see what profile they are using. They may be watching it on my profile or my wife's which clutters our watch history. If we were able to set a code for each profile, we could prevent profile clutter. Now my profile is littered with tons of kids shows and movies.

Can this be a feature request to use access codes on each profile so that when a profile is selected, you have to enter a code? For kids, there can be no code required. There are codes required for content but not profiles. Which is odd.

PS: I actually have the 4th and 6th gen devices. Not 2nd gen.
