    This allows binding "keys" to functions indirectly, by introducing a unique action, which calls your method with your parameter(s).

      Also interesting might be to only add Axis/Actions if they are not defined yet.

      void AddAxisIfNotDefined(UInputSettings* Settings, TArray<FInputAxisKeyMapping> DefinedAxis, FInputAxisKeyMapping NewAxis)
{
	for(FInputAxisKeyMapping Action : DefinedAxis)
	{
		if(Action.AxisName == NewAxis.AxisName) return; //Dont Add
	}
	Settings->AddAxisMapping(NewAxis);
}

// E.g. in StartupModule
UInputSettings* Settings = UInputSettings::GetInputSettings();
const TArray<FInputAxisKeyMapping> DefinedAxis(Settings->AxisMappings);
AddAxisIfNotDefined(Settings, DefinedAxis, FInputAxisKeyMapping(TEXT("VRSimulatorRight"), EKeys::D, 1));
AddAxisIfNotDefined(Settings, DefinedAxis, FInputAxisKeyMapping(TEXT("VRSimulatorRight"), EKeys::A, -1));

      If the user now changes the bindings, they are not forcefully added back on restart

      Note: The settings are not directly stored into the DefaultInput.ini, but in the Saved/Config/Windows/Input.ini and are copied over if changes are made in the editor UI
