Shift centre of rotation in 3D?

I'm certain I've done this before. I want to rotate a graphic away from the viewer but I want it to hinge on one side not rotate it around the centre. I guess I could offset it to one side at the track level and then adjust the offset on the parent track but that seems crude and I don't recall the answer as being that messy.

Should mention I've managed to counter my issue with aliasing during rotation. Adding a tiny amount of GB keyframed to the rotation seems to mask the problem. Not as perfect as you'd get using vectors but good enough.

In track motion - turn off "edit in object space" (3rd icon or so), and move your central point/sphere onto the edge you wish to be as your hinge. You know the rest. :)

To borrow form John Rofrano's 3D Track Motion Pivot tutorial:
Make sure the "Edit In Object Space" option is disabled.
Move the dot that's in the center of the frame in the Perspective view window to wherever you want.
Now when you rotate your frame, it will rotate around the new pivot point at the edge of the page.

Thanks guys.
Got it sorted. Would have replied earlier however my ISP managed to loose the routing tables for 80% of the planet for 12 hours AGAIN.
