How to reset the initial position of the panoramic split screen

Hello, I learned the splitscreen example. If I want to reset the perspective of two panoramas, how can I do it? Because the two panoramas were taken at different times, maybe because the camera was not completely at the same position and direction at the time, the initial positions of the two pictures were not consistent after the panorama was generated. At this time, I need Re-adjust their positions to facilitate the comparison before and after. Hope to get help.

Thank you, I used a panoramic camera to directly capture and export pictures. It is very difficult for my users to use ptgui, so in order to reduce the user's trouble, it is best if it can be defined directly on the page.

There is no online example at present, it is a problem found by development and testing.
