Automatically set the Black and the White points in Aperture?

Jasoninajeep,in this thread, refers to this Aperture Export article, which includes the helpful hint that holding "{Option}" while clicking the auto-luminance button in the Curves brick will cause Aperture to set the Black and the White points without making any other changes.

Is there any other way to automatically set the Black and the White points in Aperture?

Thanks.
