It is great that LR Mobile on iOS and iPadOS allows auto importing from camera roll. It would be even better if it was possible to select a specific album (favorites or a specified album) so to weed out extraneous photos that are in the overall roll.
I love this idea! It's the reason why I DON'T use the import from camera roll feature. If, however, I can select a folder, it will be beneficial. There's usually too much crap in the camera roll that I'd like to keep but not want in my Lightroom database.
