I have a working Lua filter and I'll be having pandoc iterate over multiple input files (for loop). However, I know in advance that my filter will only match on a specific file's data. Is it possible, within the AST model, to have the filter bail unless it's inspecting data associated with this specific file? Or do I need to deal with this at the pandoc invocation level (i.e. specify what filter to use based on the input files)?
