How to specify arguments for editor in Midnight Commander

I'm using Nano as the editor in MC, but I would like it to scroll by 1 line, which is not the default behavior of Nano.

I've found that you can specify the option -S when you run Nano to enable smooth scrolling, but I don't know how to tell MC to do that. From what I've found, you can set the environment variable EDITOR to specify your preferred editor for MC to use, but I don't know how to set any options for it.

How can I specify the options for an exteal editor that Midnight Commander uses?
