When a PI Point is the output of an analysis add the attribute path to the description of the PI Point

It can be a challenge to find the analysis that writes to the PI Points in large AF hierarchies with many contributors. It would be convenient to have the PI Point Data Reference attribute path written to the PI Point configuration (description or exdesc). The idea is to be able to trace the tag back to the analysis efficiently and without additional training or knowledge beyond basic PI System use.
