Custom content type, multiple entries grouped by day, no individual permalink?

One option appears to be a leaf bundle, as seen here:

New to Hugo | is what I'm trying to do possible?

Hi, there’s pretty much first-class support for this! You can use leaf bundles. Have a content/biographies/index.md with general content for the “list” page, and a markdown file for each person like content/biographies/jane-doe.md. No pages are generated for markdown files except index.md In the corresponding biography single page template you can do this: <h1>{{ .Title }}</h1> <p>{{ .Content }}</p> {{ range .Resources.ByType "page" }} <h1>{{ .Title }}</h1> <p>{{ .Content }}</p> …

but this would have me manually creating a duplicate _index.md for each and every day, and that’s not something I’d relish (as activities go back nearly 30 years). There’s a mention of Data sources there too, and I think I might be willing to do some sort of activity-by-day “data” $Date shortcode, but I don’t know how I’d rig it up to generate per-day lists at /activities/YYYY/MM/DD/.
