How do I create a custom post status and display it above the table of my custom post type?

Example:

All(9) | Published (7) | Custom_Status(2)

I used the advance custom fields plugin to create a dropdown which represents the status of the post. But I’m sure that that does not represent the actual status of the post since it won’t be saved in the post_status column in the database.

Feel free to suggest plugins. I tried the edit flow plugin, but it’s kinda inconvenient because every time I change the status of my post it will un-publish the post.

Thanks!
