More specific "save" error messages

I have a page with many models on it, and a “save all” button at the top. When there is a permission problem saving one of the records, the message a user gets at the top of the screen is “You do not have permissions to insert this record.” It would be way better if it says which model or object the error was related to. (Of course, in trying to troubleshoot this, users just give me the screenshot of their error, and not tell me everything they did on the page.)

Agreed! This should definitely be doable.
