Additional --filter options are not applied to included files

[josch]

Hello,

I was using https://github.com/chdemko/pandoc-latex-environment as a --filter option to pandoc. It seems that the filter only gets applied to my main document but not to the .md files which I included using !include.

Is this a supported functionality? If yes, how do I enable it?

I don't think I understand the documentation of pandoc-options in the README but adding --filter=./pandoc-latex-environment to it does not do the trick.

Thank you!
