Hi, maybe a naive question, but how to

I don't think, that is present in the Pinecone vector store code currently: https://github.com/run-llama/llama_index/blob/main/llama-index-integrations/vector_stores/llama-index-vector-stores-pinecone/llama_index/vector_stores/pinecone/base.py

You can subclass and add the method for now

you could use the pinecone client directly too
