Support named exports or preset example

[jakeleboeuf]

I'd love a way to use the barrel preset to output named exports. Is there a configuration or preset I can use to do this?

Example dir structure

project  
│
└───components
│   │   index.ts
│   │   Box.tsx
│   │
│   └───client
│       │   Button.tsx
│       │   ...

Works as expected

/* components/index.ts */

// codegen:start { preset: 'barrel', exclude: './client'}
export * from './Box'
// codegen:end

I want this

/* components/index.ts */

// codegen:start { preset: 'barrel', include: './client/*', export: 'named' }
export { Button, type ButtonProps } from './Button'
// codegen:end
