Find photos that have been published via a Lightroom Publishing Service (in particular, SmugMug)?
I've started to use the Lightroom Classic SmugMug publishing service which allows creation and publication of galleries resembling regular collections or smart galleries resembling smart collections.
I'm trying to create a separate smart collection in Lightroom which would contain all photos currently in any of those galleries, or, if that is impossible, find a way to filter the Library to show such photos.
I see an option for a Smart Collection rule called "Source/Published Via" which seems to work if I have it match individual gallery names in the SmugMug publisher, but I can't find any way to match all of my SmugMug galleries unless I enter a separate rule for each (and match on "any"). I also don't see any Library Filter-accessible metadata fields that have visibility to that type of information.
Has anyone done this, and is there an option that I'm missing?
I know that I can look in each Gallery in the SmugMug plugin (or, of course, on the target web site), but I wanted a way to identify all the pictures together.
I'm running latest LR Classic on MacOS Monterrey, but the OS shouldn't matter for this question.
Thanks in advance for any help,
Don
