Analog Input for the Gamepad Add-on by using Variables with Prefixes #9087

I have an idea for a possible way to have analog joystick input in vanilla projects that use the gamepad add-on, my idea is to let the gamepad add-on change variables from -1.0 to 1.0 but ONLY global variables that have a specific prefix like $GP_ or something, so developers can determine what variables can have input from the gamepad add-on. I feel like this would be possible to implement because the gamepad add-on can read and write comments to get and store controller mappings, so maybe add-ons can edit variables as well. I don't think it would be used too often considering most projects I see either don't need analog controller input or just use the controller extension instead but I think it would be a great addition for those who'd want it.
