I miss this feature for the same reason. I go on a shoot, or on a trip, and create a folder for the event. Shooting directly into that folder was perfect. Now, I have to go to the conglomerate “LR Camera Photos,” and move them to the desired album. Please bring back the old behavior, or at least make it an option in settings! Thanks for listening.
Lightroom CC for mobile used to be that, when a user is in an album they've created, and launch the camera, all the picture taken during that time period is processed, uploaded, and automatically added to that album. But it doesn't do that anymore, it just processed and uploaded to the main storage. Since there's no way of filtering out items not in album / collection, and raw photos takes a bit to process, is hard to find what you took and loose track.
