Hi! I'm using PropertyGraphIndex and want to customize the chunking process. So the input would not be a document, but a dictionary of chunks instead and I want all the Chunk Nodes to be from this dictionary. However, I still want to use other functions of PropertyGraphIndex to extract EntityNodes and relationships with LLM, query, retrievals etc. Is that possible and how should I do that? I looked at some directions with customizing NodeParser, but it seems that it will require me to extract EntityNodes on my own, which I don't want to.
