Spherical panoramic: how to move to precise coordinate

I am using the spherical panoramic workspace to make a video of movement within an image. I need to be able to replicate the exact same keyframes across four separate panoramics. One way to make them consistent would be to define keyframes following identical movements: 30-degrees clockwise (yaw) for example. I know how to move the viewpoint, but there must be a precise way to define a move with digits, not just with the haphazard manual glides... 

Alternately, If I create a timeline with keyframes in one panoramic can I apply the same timeline parameters to other panos? To explain my goal: I've made a series of panoramics from the same spot at different times during a construction project. The idea is to create video tracks making the same "pan" across the scene but at different points in the project.
