Vault agent k8s sidecar - sync in reverse direction, create vault secrets from files

Vault agent syncs secrets from Vault into shared path in pod so that other containers can consume them.

My question is, is it possible to do this in the reverse direction; sync from pod file system to vault, I mean, my container writes sensitive data as files into shared memory, e.g. /vault/secrets/my-secret-info and vault agent somehow creates a vault secret for this, again with proper annotations etc.

I think this is not possible today, but wondering if there are any plans or previous discussions in this regard?
