How Can I Use a Dynamic Name or Function to Change the Sanity Desk List Items?

How can I use a dynamic name or function to change what’s shown by the sanity desk list item for a document that only contains a reference? e.g. here, my 
NavigationItem
just has a reference to a 
Route
but I’d like it to display the slug of that route in the list (instead of 
route: {empty}, children: […
- I’d rather not have to add another field for a label or name

You can add a preview to your navigation item schema and pull in the slug field from the route. It will probably look something like:

export default {
  name: 'navigationItem',
  title: 'Navigation Item',
  fields: [
    ...
  ],
  preview: {
    select: {
      title: 'route.slug.current',
    }
  }
}

You might want to include a prepare() function inside of preview to handle the title when there is no route selected (e.g., when a navigation item is first created).

preview: {
    select: {
      title: 'route.slug.current',
    },
    prepare({ title }) {
      return {
        title: title ? `/${title}` : 'No route selected',
      };
    },
  },
