Refactor Idea: extract functions inside functions

[adminy]

Looking at the suggestions it says

FunctionName()
This is a big function.
Big functions are harder to understand and change.
You can refactor it, e.g., by extracting some of its logic into new functions.

This function contains lets say 3 other function definitions within itself.
These functions in most cases don't even need extra parameters,
yet when I highlight the function I don't get an Extract function to module scope.
It sounds like a safe procedure that could happen automatically or with a user action.
