Hmm, I don't see an easy way, then.
Something which you can try (it's more than a little bit of a mess)
is to exploit the debugging information which is embedded in
expressions read from files.
Take a look at this: put x:1 + y; in a file and load it via batch.
Now enter:

:lisp $x

I think that shows the debugging info (including the file name).
If you want to pursue this, I'll try to explain a way to extract it.

Sorry I can't be more helpful.
