WebStorm not resolving async webpack config

In my project the configuration has to be async, but because of this WebStorm can't resolve my alias.

module.exports = async () => {
  await doSomething();
  return {
    resolve: {
      alias: {
        '@': resolve(__dirname, 'src'),
      },
    },
  };
};

My quick fix is to create a webpack config only for WebStorm ...
