Sync iCloud based on deleted/kept photos in Lightroom

Hi,

I use a DSLR to take raw photos at "worthy occasions" and my iPhone on a daily basis to take photos.

When using my DSLR, I normally use Lightroom to flag photos with "rejected" which typically results in deletion of 80-90% of the photos captured. I would like to use Lightroom to also do this for the photos I capture with my iPhone.

Is there a way to import say 100 photos in Lightroom from the camera roll on the iPhone, flag/delete 80 of them in Lightroom, and then also delete the corresponding photos on my iPhone camera roll?

Thanks.

Best regards,

Magnus
