Keep photos added to Family Room out of the Photo tab

I just upgraded to a family account with the idea that I could categorize our photos in different folders “Christmas Photos”, “Family Photos”, each kid with photos from over the years, etc. the expectation was that the family go could into any folder and find photos they want to download or share with extended family/friends. They could do that, but the probably was ALL the photos go into everyone’s Photo Tab. What felt like my kids’ private photo backup area was now cluttered with thousands of photos, so I’m having to keep the categorized photos in my own drive and just share with my wife. 

All that to say it would be awesome to have the option to exclude photos added to the Family Room from the Photo Tab.
