Is it possible somehow to save the extracteddata to the message if the data changes dynamically. For such purposes, I used the pack stage - but I have no way to specify the labels that need to be added using pack, so the data can change.
The question is caused by parsing windows events, since different events contain different fields and it is very difficult to describe it in the pack stage. As I see in --inspect - the data is parsed, but it needs to be saved somehow.
