Using the KV store, Is it possible to have a write lock on a particular document to prevent two processes from trying to update it at the same time?

I will be using the API to work with a KV store collection. It's possible that two users will both perform an action at the same time that would cause a single document to be updated. Is it possible to lock a document while updating it so that if another process tries to do so that process will receive an error?
