We are exporting case instance data to an external Database with BIX. Main information are stored in page groups. However, we only want to export selected page groups, not all page groups.

E.g. we have multiple Locations() page groups (>5) and we only want to export two based on the subscript.

Is there a way to restrict/select the page groups to export? A when rule would be very helpful in the BIX Extract Rule.
