is there a way to ensure that a variable is always available to the diet templates

I'm using the WebInterface and have the following struct as a session var:

struct CurrentUser {
    string username = null;
    bool authenticated = false;
    bool administrator = false;
}

available to the class as SessionVar!(CurrentUser, "user") currentUser;

I'm currently getting the values off it and passing them on to the diet templates like this:

    @method(HTTPMethod.GET)
    void index() {
        CurrentUser cUser = currentUser;
        render!("mytemplate.dt", cUser);
    }

but that's horrible and can get really messy later when there's more going on. I'd like to just do:

    @method(HTTPMethod.GET)
    void index() {
        render!("mytemplate.dt");
    }

and have currentUser available to all my diet templates by some kind of global config, so my methods can focus on the data that is specific to them. is that possible?
