Photo syncing to OneDrive for multiple users, need separate upload destinations

Hi

I sync photos from my personal devices (iPhone & iPad) to a upload destination in my OneDrive account. Now one of the other named users to my account wants to sync their photos too. I followed the guidance, but the  new users’ photos started syncing to the same destination folder as my photos, mixing them all up. 
I’ve tried to see a way to ensure a separate destination folders but can’t see clear documentation on this point?

please can anyone tell me if this is possible, and if so, direct me to clear documentation as ato how to achieve it?

Thanks

Jeffrey
