Nested Event Frames of different types in PI Analysis

I am creating Event Frames via PI Analyses and was wondering if anyone had any thoughts about how to create child/nested event frames where the child event frames can have different types than the parent?


For example, if I create an analysis scheme like this:


I can get an event frame hierarchy like this when the attribute cycles through the values 1, 2, 3, 0:

However, they are all of the same template type.


I am looking to see if I can create a scheme such that the parent event frame is of one type, and then each of the children could be of different types. For example, imagine that an asset performs an operation that contains several operating modes within that single operation. I would like to be able to distinctly search for individual operating modes while still being able to retain a link to the overall discrete operation so that I know which operating mode event frames belong to each other; while the operating modes may be different.


For example, say that I wish to generate a scatter plot of the average of a tag from operating mode one and then plot that against the average of operating mode two; the operating modes are related so I must be able to link the two separate event frames together, but they are also different, so to get the correct averages, I must know which event frame was for operating mode one and which was for operating mode two. I was hoping to facilitate this search through templates rather than using tag/attribute values.


Is this something that is possible within the current version of the PI Analysis Service?
