Hi Pietro,
you can either choose the "Report all expected events" and configure a list of fields that are used the for all Expected Events (as they are listed in a table a special config per field would not make sense here) or you go the way and create configs individually per event code.
This is not restricted to Unexpected event codes you can also configure it for expected events.
To avoid double possibility of sending you should switch of the "Report all expected events" option here:
Best regards,
Steffen
