Is it possible to modify the resource path from lua?

[CodeSandwich]

I need to dynamically load markdown files referencing resources relatively. E.g. docs/03/doc.md references docs/03/MEDIA/image.png as ![](MEDIA/image.png). If I run pandoc --resource-path=docs/03 docs/03/doc.md ..., they are found just fine, but if I load the markdown file dynamically, with pandoc.read there doesn't seem to be any way to perform pandoc.mediabag.fetch that would include docs/03 as the search path unless I declare this path with --resource-path when starting pandoc. There's the PANDOC_STATE.resource_path list, but it's read-only, modifying it has no effect.
