This is supported via the CLI's startup configuration. The CLI reads ~/.copilot/config.json at startup as a global config file, where you can set model and many other options. For project-level settings, .github/copilot/settings.json is also supported, though it covers a narrower set of options. Run copilot help config for the full list of available options. If this doesn't cover what you had in mind, feel free to reopen the issue.
