# Project Source Category

The wildcard will reliably resolve to the appropriate category for the source project when utilized within a [Duplicate\_Project](/helmut4-releases/v4.10.0/helmut4-components/helmutfx/streams/fx-event-triggers/duplicate_project.md) stream.

For example: News

{% hint style="warning" %}
This wildcard is exclusive to the [Duplicate\_Project](/helmut4-releases/v4.10.0/helmut4-components/helmutfx/streams/fx-event-triggers/duplicate_project.md) stream.
{% endhint %}
