Missing photos in iPhoto's Photo Stream

Sometimes I take photos around my construction site, I got a MBP inside my office connected to Internet (sometimes intermittent), when I get in the Wifi area mi iPhone uploads it to Photo Stream with no problem. Issue is when I open iPhoto in my MBP, I am missing one photo, so I got to turn off Photo Stream in iCloud preferences and turn it back on and it downloads all photos again, isn't there a way to force it to sync so instead of downloading all again, it only download the missing photo?

Thank you.
