No, because the document gets broken up in the ChunkedHTML writer, and the filter runs before the writer.

However, in lua (via the pandoc.structure model) you have access to the function pandoc will use to split up the document, so you can split it up yourself and then you should have the data, as long as the parameters you use for splitting are the same as what the writer will use.
