Setting to have azure function folder not at the root level

[nicofraisse]

In Javascript, from the documentation, the default folder structure is at such:

FunctionsProject
 | - MyFirstFunction
 | | - index.js
 | | - function.json
 | - MySecondFunction
 | | - index.js
 | | - function.json
 | - SharedCode
 | | - myFirstHelperFunction.js
 | | - mySecondHelperFunction.js
 | - node_modules
 | - host.json
 | - package.json
 | - extensions.csproj

I would like to have this structure instead:

FunctionsProject

 | - src
 | | - MyFirstFunction
 | | | - index.js
 | | | - function.json
 | | - MySecondFunction
 | | | - index.js
 | | | - function.json
 | | - SharedCode
 | | - myFirstHelperFunction.js
 | | - mySecondHelperFunction.js
 | - node_modules
 | - host.json
 | - package.json
 | - extensions.csproj

The documentation partly addresses this by using the scriptFile option in function.json, enabling to customize the entry point file location, like this:

FunctionApp
 | - host.json
 | - myNodeFunction
 | | - function.json
 | - lib
 | | - sayHello.js
 | - node_modules
 | | - ... packages ...
 | - package.json

However this does not enable having the function's folder (the one containing function.json) itself moved to another location than the root level, in order for the function to be detected.
Is there a clear, or even hacky way, to acheive this currently? If not I think it would be nice to have this flexibility.
