Lightroom changing order of photos edited in Photoshop - help!

When I edit a photo from outside plugins like Photoshop, the images move to the end of the filmstrip. How do I keep them in the original sequence? I cannot sorting them by name/timestamp as I often create custom orders (I work with weddings), so I can not simply switch back to sort by timestamp again. It would be really helpful if a newly created image (happens also with the new denoise-feature) would order itself next to the image with the same name. Otherwise I have to scroll back and forth  for 1000 images to put it in the right spot again. Can you please help me? I am using Lr Classic, latest version, in a mac.
