Filter out “Previously Added” on import

At the moment the only filter options in the import screen on LRCC-iOS are “Photos”, “Videos” and “Raws”.

Please add more filtering options in the import screen... at least the option to filter out photos/videos that were already “previously added” in order to quickly identify them (without having to scroll hundreds of thumbnails looking for photos/videos without the small “Lr” overlay.

Thank you in advance.
