Both full and summary RSS feeds?

Is there a way of generating both full and summary RSS feeds for the same content?

You can do so with https://gohugo.io/templates/output-formats/.

I guess I’m not seeing how. Aren’t the templates keyed by media type? In my example, I have the same media type for both full and summary RSS.

Right now I have layouts/_default/rss.xml . Where would I put / what would be the name of the other template?
