I'd like to know if I can set up multiple different folders, in different locations (OSX) to sync to Photos?
I expect not. Currently I have to copy all the photos I want on the iPad, into one single directory on the Mac (which I call iPad Portfolio), with subfolders for additional categories - because there is only one sync source in iTunes.
At least in iPad/Photos.
I'd love to be able to browse the Mac in iTunes and select multiple individual photos or folders to sync for multiple locations without having to redundantly copy them all into one master "sync" directory...
