library.import gains destination (copies go there instead of the library's Originals/; no
library needed), organize (date | month | flat), rename (file-name template with the rename

metadataPreset. The Add Photos dialog: Copy → Copy to (Choose… / Library), Folders, Rename with
a live example, Metadata preset; batches keep the numbering going.
