How to preserve folder structure?

The natural location of .md files (for me) after the conversion is: each .md file is in the nested folder named after notebook/stack/whatever-i-see-in-evernote-ui-as-a-folder. How to achieve that?

```
## before (in Evernore UI)

/folder
  /subfolder
     /subfolder
        note 

## after (on disk)


/folder
  /subfolder
     /subfolder
        note.md
```
