Is there a way to track the splats to the images?

Hello,

With COLMAP, it is possible to extract data to determine which images and keypoints correspond to specific 3D points and to identify which images have been matched.

I am wondering if it is possible to track which Gaussian splats correspond to which keypoints, along with their associated image files and pixel coordinates. Is there a way to "tap" into the code to keep track of this when using Nerfstudio?

Specifically, I want to identify the originating image and pixel coordinate for each Gaussian splat (with respect to the point cloud, not the splat itself). While COLMAP provides this information for 3D points, I would like to know if it is possible to extend this tracking to the exported PLY file for the splats.
