Replace DTPO PDF preview with Apple OS Preview?

Snow Leopard’s preview is more functional than the default PDF preview in DTPO 2.0. Is there any way to change the default PDF viewer in DTPO to Apple SL’s Preview so that when I double-click on the file it opens with SL Preview?

I have the “Open with External” button up on the toolbar, but it would nice if SL Preview would be the default app when I double-click on the file icon.

Thanks.
Bud
