如何用PHP-CS-FIXER移除多行三元运算符的多余缩进？

能否通过PHP-CS-FIXER移除多行三元运算符的多余缩进？实际场景中真假分支内容往往较长，使用多行写法可读性更强。

当前代码：

<?php

class Test
{
    public function __invoke($var = 100): bool
    {
        return $var = 100
                        ? true
                        : false;
    }
}

期望效果：

<?php

class Test
{
    public function __invoke($var = 100): bool
    {
        return $var = 100
            ? true
            : false;
    }
}

我的PHP-CS-FIXER规则配置如下：

我原本猜测ternary_operator_spaces是最相关的规则，但它仅能修复单行三元运算符中条件之间的空格问题，无法解决多行缩进的问题。
