Animating look-at while in a dolly track

Hi.
I have a virtual camera on a dolly and I would like to animate where it’s looking at.
I tried changing the look-at object, but it just snaps to the new one.
What I want is to control the gaze of the camera, for showing off the scene. What is the right setup for this?

I tried creating one camera per look-at target and then blending between them, but then the other cameras are not moving. I tried setting the other cameras to follow the first one, but even if I set Body to Transposer in each and set offset to 0 and damping to 0, they don’t exactly follow the path of the first one’s body. Hard-lock doesn’t even move, only aims, even though it’s in the Body setting of the VCamera.
I thought of two simpler (but not very easy to control) ways:
-Animate the camera angle (if I change the track position it will break though)
-Animate a target object and just set look-at to it (Means fiddling with a proxy object)
How should I approach this?
Thanks

I think your best bet is to animate a target object and look at it. You can mix that method with blending between multiple vcams where appropriate. The more you can decouple your animations (e.g. separating track positions and camera angles), the more robust the solution will be.

Oh,
Thanks.
