Way to differentiate "root" description from "default command" description

Right now, it seems that the description listed above the Commands section is just pulled from the description field of the default command. I have a use case where I want the "root" level tool description to be different than what is shown in the line for the default command. Is this possible? And if not, can there be an option for that (I'm thinking it would be similar to the scriptName method, maybe scriptDescription?)

Current

$ npm start -- --help

> software-update-checker-cli@0.4.0 start D:\Repos\software-update-checker-cli
> ts-node src/index.ts "--help"

software-update-checker-win.exe [add|view|edit|remove]

Check if installed software has updates available

Commands:
  software-update-checker-win.exe [add|view|edit|remove]     Check if installed software has updates available [default]

Desired:

$ npm start -- --help

> software-update-checker-cli@0.4.0 start D:\Repos\software-update-checker-cli
> ts-node src/index.ts "--help"

software-update-checker-win.exe [add|view|edit|remove]

Check if installed software has updates available

Commands:
  software-update-checker-win.exe [add|view|edit|remove]     Launch interactive console [default]

No yargs files or tests are named; the example identifies src/index.ts as the consuming entry point and mentions the existing scriptName method. Start by tracing --help output and how the default command description is reused, then verify that the root and default-command descriptions can be supplied independently.
