P: Mark duplicate photos with an icon and provide more filters in the Device tab

In the Device tab on the iOS app, please mark duplicate photos that are not imported. This would help the user identify duplicates in their camera roll and remind the user to not to try to import the duplicate photo again.  (The app marks photos that have been imported already with an LR symbol. So it seems possible to mark duplicates.)

Also in the Device tab, please add filters for duplicates and imported photos so the user can display only photos that are not duplicates and/or have not yet been imported into Lightroom.
