Iphone app

I have a Duo that backs up my photos from iphone. Really nice that i can see them sorted by month under the Photos header in the app. But I have recently copied another photos folder from my laptop to the disk and apparently they got a creation date feb. 2020… so now instead of order I have a chaotic mix of photos spanning a decade.
Is there a way to only show the photos synced from my iphone in this part of the app?
