I’m looking at setting up another device as a “semi-vault” to help with syncing in our home. I’d love an option to be able to sync originals (or previews) for any photo within the last X days or months. I’ve got space on lots of devices for all the images from the past year… but don’t have space for everything going back decades. Wouldn’t want to be manually tagging or keywording to make this happen. If I need an original from 1995, I’ll just get that from the vault device, but more often it’s something from just last week.
If you organize your last year’s photos into the same folder, then you cna set that folder to be sync as originals on a device by device basis.
