resolvePaths on true and change root folder

[youg009]

Hello
is it possible to define the root folder with resolvePaths ?
My problem is that my root folder is a sub level to my gulpfile.js file

Exemple :
|-root
|--dist
|---subfolder
|---css
|---js
|--- index.html
|--node_modules
|--src
|---subfolder
|---sass
|---js
|--- index.twig
|--gulpfile.js

Thank you
