Batch Autostraighten in Lightroom CC

I have been scouring the community discussion groups for an answer but I dont find any that works for me. 

I have a set of 2000 pics that I took of a stage performance. As all these photos were shot handheld, there is a slight straightening issue with each pic. I use Lightroom CC web-based (not Classic). When I go to each photo individually, go to Crop menu, and click on Auto on top of the slider that says Straighten, it does a decent job of straightening the photo. However, there is no way to copy only the auto straighten part and paste it to the rest of my photos. If I choose settings to copy, I can choose options - "Crop" "Upright" and "Manual Transforms" but they don't copy the auto part of the straighten and paste it correctly on a new image. But if I go back to the same Crop menu of the new photo, and click on Auto, it straightens it! With a slightly different angle than what was pasted! Does not make sense. Am I missing something? Is there a way to autostraighten a batch of pics easily?

I have also tried the Upright --> Auto option under Geometry. That does not work as well.
