Android: create new folder without adding new feed

Using NewsBlur has been a joy for several years. I occasionally have wanted to change how I organize my feeds, but I can’t find a way to add new folders without subscribing to a new feed. A way to create new folders directly, or from the Choose Folders menu for an existing feed, or in a dedicated folder management view, would make this much easier. Thanks!
