Is it possible to set content related permissions on cartalyst/sentinel?

i'm new to laravel and cartalyst/sentinel, but for this project i'm facing out an authorization problem: I have to set User CRUD permissions for the single content, and i'm facing out how to do id with cartalyst/sentinel. (a lil' example: if i have a blog, i wanna set User CRUD permissions separately for each article). Can anyone help me to find some documentation about something like this? I have already implemented this kind of permissions with CakePHP, but is the first time i'm using laravel. Thank You
