So my Android Videostream app seems to sometimes work great in organizing SOME of my videos. You can see in the attached screenshots that it figures out that I have multiple seasons of "Game of Thrones" and clusters them together, and then expands them when I click on that. However, I have a bunch of "Extras" for Game of Thrones as well, and those don't get organized well. You can see in the screenshot that those Extras are all individual files cluttering up my library list.

What metadata does Videostream pull to organize the files? How would I go about editing that so I can create a subfolder in "Game of Thrones" that clusters all the Extras together (similar to how each season is clustered together)?

Thanks,
