P: Subject Aware Crop Sync Across Numerous Images

I'm a wildlife photographer who has just returned from the Arctic. As I'm editing, I find myself with aproximately 1,000 images in sequence of an interaction between a polar bear and a walrus, in which the polar bear wakes a sleeping walrus on the pack ice who is obviously startled. What would be helpful is a crop feature in which the main subjects, in this case the polar bear and walrus, remain centered in frame across thousands of synced crops. This would solve having to manually recenter thousand(s) of images.
