Exporting default from subdirectory

Question

Suppose I have a file structure that looks like this

–Directory
--myComponent.js
––Subdirectory
–––fileA.js
–––fileB.js
–––index.js
––index.js

My Directory/Subdirectory/index.js looks like this:

export { default as fileA } from './fileA';
export { default as fileB } from './fileB';

My Directory/index.js looks like this:

export { default as myComponent } from './myComponent';
import * as _Subdirectory from './Subdirectory';
export const Subdirectory = _Subdirectory;

My question – can line 2 and 3 from Directory/index.js be written as a one-liner (just like line 1)?
