Rsync include support

There seems to lack support for rsync include option
 I tried to add the include the option 
```
rsync__exclude: [
        ".git/", ".idea/", ".settings/"      ],
      rsync__include: [
        ".settings/foo" #something i expect to be passed to rsync but nothing changes 
      ]
```
How can i achive that with the latest build?
Thank you !
