Actually not really. I have them set as groups and tagging is super easy. You can play back the groups as a video, hit pause, adjust to the frame you want and tag it. Then when importing into photomechanic sort by just the tagged images and boom! 10k can drop to 100 that easily.Just catching up on this thread as I've been away.
As a ex pro sports photographer you have created the perfect nightmare, 10K images to go through and dead line in 30mins!!!
