hi @phgoddard!

Have you seen this post?

You may have seen it, but we have a similar write-up of how to nest labels in [our documentation](https://prodi.gy/docs/text-classification#large-label-sets).

Also, if you have a lot of sub-label names (e.g., 10-20), you may find the [`text_input`](https://prodi.gy/docs/api-interfaces#text_input) and its `field_suggestions` to be helpful instead of listing out all sub-labels in the `choice` interface. Adding `field_suggestions` can allow you to have a box with auto-suggest and auto-complete to fill in answers. However, it's worth noting that providing too many labels, may have its limits too.

Hope this helps!
