Hey there,

The best way to do that would be to create an ideabook for each of the categories that you want to keep track of. That way, when you chose to save a photo, the site will prompt you to choose which ideabook you would like the photo to go in. Here's an article on how to create ideabooks https://www.houzz.com/magazine/how-to-create-and-use-ideabooks-stsetivw-vs~19764256 Hope this helps!
