How to pick photo albums on devices to backup

I posted in the Mobile apps too but not sure if anyone is seeing it.
How are people handling photo uploads to MCH from their phones / devices? I am noticing that I am getting duplicate uploads from the photo backup because the app is uploading both my Photo Album and my Photo Stream on iOS. Unfortunately I’m not seeing a way to select albums to backup which is frustrating.
Are other people experiencing this and are they figuring out a way to manage the duplicate files on their MCH? I really don’t want to have to go through thousands of photos to remove duplicates.

As far as I know theres no way. Bums me out, too.
