Export Primary Key from a broadLog Schema



I need to export the primary key (broadlogid) from the broadLogRtEvent schema for a daily log file extract.

In the Extract file activity there's no option to export the primary key (see attached image).

Adobe's online documentation states "It is not possible to export unique identifiers (primary keys) of log resources." However, there must be a way around this using a different approach.

Does anyone have any ideas on how to export the primary key from an Adobe out-of-the-box schema?

Thank you,
