Fusion: 3D and object tracking at once?

I am kinda safe when it comes to camera track a clip and i am able to put something in the scene.

But i would like to track an object in a clip with a moving camera. Means, i want to 3D cameratrack the scene and within that tracking an object including the camera track data. Is that possible? And if yes, how should the node tree looks like?

Cheers

Thomas
