Introduce more granular checked data checkbox along with an API

Introduce more granular checked data checkbox along with an API.
I, Pierre, using HungerGames, would like for instance to be able to check ingredient lists.

I would pass:
code=1234&check=ingredient_text_fr&user_id=xxx&pass=xxx

Depending on my status as a proofreader or not, the front would display a green tickbox that on hover would display: "French ingredient list check on July 6th at 12:22 PM by teolemon"
It would also be returned by the API so that we can expose it in the app

We already have a checkbox for the whole product, but that doesn't allow for much flexibility and scale
