Are you talking about iPhone photos downloaded into Lightroom Classic? You can set the download location in the Lightroom preferences. Choose any folder you like. Then you can add the option to create subfolders by capture date.
ok, I guess I should have said "synced" iphone photographs. I can see them at the top left when I open LRCC under "all synced photographs", but I would like to have them moved to my folders and separated by date. Thanks.
