Hi, I am using SimpleDirectoryReader which works great, but I am having trouble with having just a simple identifier on documents which get chunked up (because they're too large). I notice it just creates new ids and links it with Relationships, but I wish to have a simple id on each part of a document which is the same. Is there such a thing?

I have also added an identifier to the metadata_fn, but it feels like something LlamaIndex should be supporting in some way or another. Am I overlooking something?
