I want to go through my collection of Movies & TV show and tag / assign custom category to many files quickly. Specifically, I want to categorise all Marvel and all DC movies and TV episodes so that they show together under a custom category on the poster wall, or something equivalent. What's the best way to do this? I can't find a way to multi-select files and assign them to a category. I don't care if this is done through the web based GUI or with the remote, but I do not want to have go to each item individually. I'd spend more time tagging the shows than watching if I was going to do them one by one.
