Request: continuation indent on hanging line

[bwbb]

Consider the following code:

const httpClient = {
  ...axios,
  postDataWithAuthToken<T = any, R = AxiosResponse<T>, D = any>(url: string, data: D, authToken?: string): Promise<R> {
    const config: any = {
      headers: { ...baseHeaders },
    };

    if (authToken) {
      config.headers.Authorization = `Bearer ${authToken}`;
    }

    return axios.post(url, data, config);
  },
};

Formatted as follows:

{
  "lineWidth": 100,
  "bracePosition": "maintain",
  "operatorPosition": "nextLine",
  "preferHanging": true,
  "preferSingleLine": false,
  ... 
}

const httpClient = {
	...axios,
	postDataWithAuthToken<T = any, R = AxiosResponse<T>, D = any>(url: string, data: D,
		authToken?: string): Promise<R> {
		const config: any = {
			headers: { ...baseHeaders },
		};

		if (authToken) {
			config.headers.Authorization = `Bearer ${authToken}`;
		}

		return axios.post(url, data);
	},
};

It would be nice to have an extra indent on line 4 of the formatted code, for better readability. In editorconfig and Jetbrains products, this feature is called continuation_indent_size.
Also please add a feature to optionally have a new line after the hanging line. With these settings applied, the formatted code would like like this:

const httpClient = {
	...axios,
	postDataWithAuthToken<T = any, R = AxiosResponse<T>, D = any>(url: string, data: D,
			authToken?: string): Promise<R> {
			
		const config: any = {
			headers: { ...baseHeaders },
		};

		if (authToken) {
			config.headers.Authorization = `Bearer ${authToken}`;
		}

		return axios.post(url, data);
	},
};
