You're correct, I'm trying to copy the folder structure without the files when "traveling". Sorry I didn't explain that clearly.
I file by location, so for example, the first time I go to Washington DC, I create a "Washington DC" folder with sub folders for "Capitol", "Washington Monument," "Lincoln Memorial," etc. Within each of those sub folders I have an "Edited" folder for the PSD files a "JPEG" folder for the final JPEG's. The next time I go to DC, if I can copy that folder structure onto the laptop without the images I don't have to recreate it from memory. Then since the folder structure matches what is already on the main storage drive, the ingest folder function would work perfectly to transfer the images back to the main storage drive after I'm done editing.
If I have to create the folder structure from memory there's a chance that I don't get the folder names exactly the same as last time and then end up with duplicate folders on the main drive that require cleanup.
Adding a "travel" function that can copy a portion of the folder structure off the main storage drive onto a laptop would be useful for anyone who files by location like me, any wildlife photographer who files by species, any sports photographer who files by team and player, etc.
