How to get Rider to work with .csx C#Script files

I would like Rider to recognize .csx files as being C#Script files, and use C# formatting settings (editorconfig, preferably, which is what we use), and read the appropriate DLL's referenced by `#r` directives, and include other script files loaded with `#load` directives. Perhaps there is a way to do this already? If so, anyone know how?

For now, I am having to drop to VSCode for C#Script files. Any suggestions welcome.
