How to customize Python Intellisense documentation format in Vscode?

Question

This is the same that Paul wanted to do in Create Custom VS Code Intellisense Documentation

The thing is that I am working in quite big project that doesn't use the standard Python docstring ("""documentation"""), instead they use the following format:

# DESCRIPTION:
#   Adds two numbers
# PARAMETERS:
#   a - first number to add
#   b - second number to add
# RETURNS:
#   Sum of a and b
def add(a, b):
  return a + b

I would like that Intellisense shows me this documentation whenever I hover over the add function wherever it is used, but since the project doesn't use docstrings this doesn't happens.
