To do what you want the object always has to be loaded with the insert id which means an extra function call and then it is the question how to handle the result_array method, should the insert id be added or not?

Although it isn't impossible to do you will not always use it. I think it's a good thing not to load more than you need.

You could create a method where you add it to the result and call that function.
