Josh,
So one of the concepts discussed at the Kimball training was around audit metadata and tracking the objects and actions that get a Dimension or Fact to its final result. This definitely seems like it could be valuable but also could require a lot of effort. Unless it is a firm business requirement, it isn't likely to be implemented due to the large amount of time and effort to track and document the lineage.
However, some of the tracking might be already done for you!
