Question regarding custom post type and needing to add a private yes/no toggle to admin page.

I have created a custom post type called broker-view. I have added my own custom login and have used the page creation function of the custom post type in the admin to create all my pages for the app.

Pages Created:








I am using the Session to store the login data. Once logged in I want to make the reports available. I am well versed in writing php code and pretty familiar with wordpress.

So my question is how do I add a yes/no toggle to the edit page of the brokerview post type that is simply for distinguishing the pages that require login. Obviously I can code it for every single page but would like a cleaner approach where all I have to do is select yes/no and this creates the desired behavior. Again I am a custom login and table to store only brokers.
