Using the templates while having subfolders to organize photos and videos of different cameras

Hello all,

I have a folder structure that looks like below,

shoot-name-for-client-A

  photo

  video

When I want to export, I thus cannot use the Folder Name template to rename the exported files since it creates names like "photo-xyz" instead of what I want "shoot-name-for-client-A-xyz". Is there a template for upper level folders?

If not I also saw that there was something called Shoot Name that is set during the import, since I have around 100K pictures already imported, is that possible to set this after an import? In any case "Shoot name" doesn't show up among available templates but I'm hoping that it will once it is set in the metadatas or something.

Thanks for any help.
