When uploading, there should be a feature to group the same photos to make organization / sorting through easier and less time consuming.

Photoshop only works with individual documents. It doesn’t help organize whole folders of images. For that, Adobe has other applications.

If you want automatic gathering/grouping, as others have pointed out that can be done using the “stacking” feature of the organizer applications Adobe Bridge or Adobe Lightroom Classic, where you can “stack” photos as if you were organizing photos by stacking piles of photo prints on your table. 

Both let you manually stack photos, but because you are asking about automatic stacking, I’m not sure if Adobe Bridge does that but Lightroom Classic absolutely does. Pictured below is the dialog box that appears in Lightroom Classic if you choose the command Photo > Stacking > Auto Stack. You can see that it can try to auto-stack by how closely photos were captured at the same moment, or visual similarity.

As ExUSA noted, the Assisted Culling feature in Lightroom or Lightroom Classic, shown below, can help quickly narrow down photos based on which ones are in focus, exposed properly, etc. It can also automatically stack photos for you. 

Photos that don’t meet your criteria can be assigned the “rejected” flag so that you can review them as a group before deleting all rejected images at once.

Lightroom now has an Assisted Culling feature, you might look into that.
