Good question like if the data grows and you want to to re-import the file? If so then it is not too hard to either import it again (just the changes) or honestly just delete the source and re-import it that way, Since the transformers will rerun the steps to turn the data into embeddings.

I am about to show webhooks and wehook listeners which might help but that might be overkill for this.

With it you could trigger a new import (coming soon)
