"class session" level creation

Hi,

I'm a french math teacher, so i'm sorry for my poor english level.

I would like to be able to create a "class session" level where I could attribute some videos, lessons, exercizes for one hour in classroom with my students.

It would be interessant to be able to attribute a "class session" to different classes.

Do you need more detail to be understood my need ?

Thank you very much !

Alex.
