Convert bounding box to smart polygon in bulk

I was wondering if there was a way to convert bounding boxes to smart polygons in bulk? I have over 2,000 images with bounding boxes that I need to change to smart polygons. I’ve done a few hundred just by going through each image individually and converting, but I was hoping there was an easier/faster way to do this. The program I had annotated these for had initially requested bounding boxes, but with a new update, they are requesting smart polys.

It would almost be quicker for me to delete all the annotations on these photos & re-do them using SAM3, but I can’t find a way to clear those out either.

Any help would be greatly appreciated! Thanks.
