Remove dir name from autogenerated index.md directories?

[scottyob]

My sidebar is configured by:

    starlight({
        title: 'Leaf',
        social: {
            github: 'https://github.com/DangerMonkeys/leaf',
        },
        sidebar: [
            {
                label: 'User Guides',
                autogenerate: { directory: 'user-guides' },
                // items: [
                //     // Each item here is one entry in the navigation menu.
                //     { label: 'Example Guide', slug: 'guides/example' },
                // ],
            },
            {
                label: 'Developer Reference',
                autogenerate: { directory: 'dev-references' },
            },
        ],
})

Given the desire to co-locate images with the markdown docs; my folder structure looks like the following (note index.md)

I end up having an extra, un-needed layer in the sidebar. Can I configure this in some way to know if a directory doesn't have any children, and it's accessed through index.md, to remove this from the tree?
