Can I share individual movies and a complete Library to Users

I have setup 3 libraries.
Films
Kids
TV Shows

I have 3 children who only have access to the Kids Libraries, however, I want to share some of the movies in Films. I add a Label under Sharing of the movie, and then add that Label to the user, but he can only see that movie, his access to any movie in the kids folder is gone. Even though he has access to it. Anyway around this without having to go through 300+ children’s movies and adding labels to all of them? Can I just add a label to the Libraries?

Sorry can’t add label to library. If you can’t just add the allowed ratings restrictions of like PG, G because some of those are in other library too.You can label 300+ movies in about 5 seconds.

go to kids library
Shift click on first movie.
scroll to bottom
Shift Click on last movie

all should have an yellow outline and number on top left indicated they are all selected.
click Pencil icon on top right to edit all at once and add the label and save

obviously when you add new movies to the kids library you will need to remember to add the label

My suggestion is you have 4 folders
Kids - kids only stuff
KidsOK - movies ok for kids
movies - all other movies!!
TV - as before
You point your sons user to kids and kidsOk and TV if you want
You and default users sees all four folders…
