Laravel渴望即时加载关系

有没有办法使此代码看起来更漂亮，将这两种方法合并为仅一种？

    /**
     * With authenticated user's rating
     *
     * @param  Builder $query
     * @return Builder
     */
    public function scopeWithAuthUserRating(Builder $query): Builder
    {
        return $query
            ->when(auth()->check(), static function (Builder $query) {
                return $query->with('authUserRating');
            });
    }
    public function authUserRating(): MorphMany
    {
        return $this->morphMany(Rating::class, 'rateable')->where('user_id', auth()->id());
    }

The authUserRating() method only exists because I need to define that relation for the scope method that needs it right above. In other words, is there an elegant way to refactor these 2 methods into just 1? I am looking for something like this : 

    /**
     * With authenticated user's rating
     *
     * @param  Builder $query
     * @return Builder
     */
    public function scopeWithAuthUserRating(Builder $query): Builder
    {
        return $query
            ->when(auth()->check(), static function (Builder $query) {
                return $query
                ->with(
                   $wtf_am_i_doing->morphMany(Rating::class, 'rateable')->where('user_id', auth()->id())
                )
                ->as('authUserRating');
            });
    }
