Use Event Frame attributes as inputs to Event Frame analysis in the Outputs at close section

It would be nice if it was possible to access Event Frame attributes in the Outputs at close section of an Event Frame analysis. Use case: I have an event frame generation analysis and I would like to write a few outputs to the event frame on close. I want to write outputs based on the duration of the event frame and whether someone has already edited the event frame while it was open.

    The current release supports the EventFrame() function. There are 3 options: "StartTime", "EndTime" and "Duration". If an event frame was created by PI Analysis Service, we advise users not to use a different client to make changes to the event frame. There is a possibility that PI Analysis Service would not be able to close the event frame if a different client has it checked out.

    This originated from my PI Square post. The ability to run an analysis on event frame close is useful, but I think it is pretty limited unless you can refer to other event frame attributes during that analysis. In the original post it was suggested that this could lead to a circular reference, but I don't think that should be an issue since the analysis is guaranteed to only run once, at event close.
