How to specify the root to start scanning if you only want to export 1 node

[dotnetshadow]

Hi there,

Thanks for a great package. I'm just wondering when using the "Includes" property in appsettings such as

Includes: /foo/bar/hello

While this will technically export the one path, it will still require scanning the whole content nodes until it finds that node.
Is there any setting that can be applied to tell usync to scan only from a certain path?
