is there a way to change/update vectors in index?

Hi FAISS community,

I am considering using faiss in a setting that I dynamically update the vectors added into the index.
E.g., I may want

import faiss                   # make faiss available
index = faiss.IndexFlatL2(d)   # build the index
index.add(xb)                  # add vectors to the index
index.update(ids, new_vecs)    # a hypothetical method that updates the vectors of ids to new_vecs

Is there a way to do this in faiss?

Thanks very much in advance!

Best
