How to change background of Org-mode's source code block only from the indentation of #+BEGIN_SRC?

Question

In Org-mode, I wonder if the background color of the source code block can be changed only from the indentation of #+BEGIN_SRC?

Here is the current background in my Org-mode:

Is it possible to change its background to something like this? Note that the background of the first few columns of the code environment is unchanged.

There's no simple configuration option that you can change to do this; you would need to change the org-mode code.

That said, you should be aware that the content of the code block includes the spaces at the beginning of the lines.
