I'm afraid this isn't possible without an override of the internal UsersController

okay, I have added an array key value after line 172. It shows up, do I need to do anything else inside the controller?

You're using twill 2 or 3? If you're on 2, it's the same as how you define the navigation in twill-navigation.php, so you can use

route

and pass a route name (instead of

'module' => true

)
