Not sure if this is beyond PM functions, but it would be great if the sound sound/wav file from the camera would stay with an edited/toned image...
My work flow may be different from others, but I always have two folders open in PM during an assignment: RAW and EDITED.
I ingest into the RAW folder. After pulling a file from the RAW folder (w/ sound note) into PS or Lightroom, I then save the same file renamed into the EDITED folder.
With the image in the EDITED folder, I no longer have the sound clip that was originally attached to it, and must go back into the other folder to find the sound clip.
Thanks.
