Log UUID in Events metadata generated by an API Batch Call

It's possible to execute a number of operations via a single call to the API batch method. This helps reduce the number of server roundtrips, but it can sometimes make it difficult to sort out all the Events that were generated from a single batch call.

This request is to add a UUID to the meta value of Events so users can easily identify from which batch a given Event was generated. Would this be useful to you? Add your vote and additional use cases below.
