I suspect that what you are asking for probably breaks the current nginx
processing and logging model, and would probably require significant
code changes.
You are welcome to submit a patch for it -- after either having written
one, or incentivised someone to write one for you -- and it will
presumably be considered for inclusion in the stock nginx code.
(And if it isn't included in stock, you can always use it in your
version.)
But you may find there is a simpler way to achieve your desired end
result.

As you probably know, that will do what you say you want if the file
$document_root$uri is present, and not otherwise.

As you say, you can change the config to match what nginx does to what
you want.
Alternatively, you could possibly post-process the log files to end up
with what you want -- either read the old log files and split the contents
according to what you want; or maybe have nginx write to a stream, and
have your own processor reading that stream and writing each log entry
to your desired place for it.

I suspect: only if you provide the code to do so.
