In Piano Analytics, there is only one database for all events (single table).
Therefore, when configuring your Data Flow exports, you can choose which properties are displayed, but not which events are taken into account. When you select the "All events" option in the configuration, all events are sent in each Data Flow export.
If you need to filter on a given type of event, we invite you to add the "Event" property, and then, afterwards, to filter the values (on "starts with click." for example for standard clicks).
