Generate STM32 MCU pin configuration automatically on MCU

Building a project for STM32F4-Discovery I realized it's really hard to keep track of all the pins as they get configured in different files all over the project. It's either keeping a separate list of assignments and functions (maybe using STM's cube software) or just going through source files every time.

Or maybe just having MCU report how pins are configured?

Here's what I managed to get out of my STM32F407VGT6:
==============================
