I don't believe you can. When you save a container with no children, I think it will revert to a non-container.
But if you change the container_suffix System Setting to /, it might help with your problem. That's what it's normally set to.

I tested it and containers without children do show up as url.com/container so I will just make everything a freaking container. Not ideal, but it works.
I'd wager my ssl certificate is causing issues, but then again I can't be sure.
Thanks for working with me on it.
