How to save words to a smaller list

I don’t know how to study words from one program at a time.

When I look at all the words I’ve saved, the source is in the right-hand column. Ex. Netflix or YouTube and it also links to the source. This is great! I would like to be able to create smaller lists or categories so that I can specifically study words and phrases from one movie or program. Is there a way to do this. Under the “sources” I see “word list” but I don’t see a way to save words to a word list.

If somebody knows how to do this, please tell me. If it can’t be done now, I hope it will be added soon as a feature.

Thanks for your help :slight_smile:
