Improve on the current group cull tool to better group by selecting a reference subject photo

I photograph motor sports shooting multiple cars throughout the day. I would like to speed up editing and culling after the photos are imported into capture one. I would like to select a reference car to display all cars matching or very close to that car for quick culling and editing.

Current workaround

It is a slow painful process of scrolling through images looking for all versions of the same car.
