Parental control on Movies in the library

I have noticed that you can do parental control on Folders rather than individual movies. For me, I have 2 folders which are Movies & Cartoons. As far as Movies folder it contains lots of movies that kids can watch like Home Alone or even adult films that have no sex or sex talk.
Is it possible to have a passcode that can be set by the Admin which needs to be entered to each movie that can only be watched by Adults? and this passcode I can share even with family & relatives whom I will share my library with?
Lets say I have the movie Indecent Proposal in my Movies folder, and my son tried to access it out of curiosity, he gets this passcode request, but if he goes to Home Alone, he can watch it without any passcode. Is this possible with Plex?

It’s not.
