How to track multiple batches in EventFrames on a production line?

Let's say we have a production line, consisting of a reactor vessel, a separator, a holding tank and a packaging machine, connected in sequence. A batch is run in sequence on this line, and i want to capture in an EventFrame various values, e.g. the time of starting end ending operation in one of the Units.


Now i could do this by defining an eventframe on the line in AF, and capturing the values / timestamps i need through standard use of Analytics. 


However, a new batch can be started at the reactor vessel, while the previous batch is still in the holding tank, and the batch before that is in the packaging unit. So i would need multiple EventFrames in parallel.


Any creative ideas how to achieve that?

End goal is to use an EventFrames table (well a custom one as the standard table does not allow including attributes) to show me a list of the last 20 batches or so, and the values of those eventframes.


PS: this is of course a simplified example
