如何对齐森林包中某些级别的边缘？

Question

我有一个两列的文档并创建了以下树：

如您所见，第三级与另一列的文本重叠。为了解决这个问题，我想将子节点Hotel1234567890和Golf12345略高于其父节点，将Lima12345678和Kilo12345略低于父节点，以有效利用空白空间。

理想的最终结果应该是这样的：

代码：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{forest}

\title{Bla}

\begin{document}

    \begin{forest}
    for tree={

      parent anchor=east,
      child anchor=west,
      align=center,
      l=1em, l sep+=0em,anchor=base west,inner sep=0.1pt,outer sep=0pt,
       edge path={
                \noexpand\path [draw, \forestoption{edge}] (!u.parent anchor) -- +(5pt,0) |- (.child anchor)\forestoption{edge label};
            },
      for root={
        parent anchor=east,
      },
    }

\end{document}

我认为可以通过为这两种特殊情况创建两种新的边缘样式来解决此问题。但是，我不确定需要如何edge path设计才能满足这些要求。

像这样：

\usepackage{showframe}
\usepackage{lipsum}
\usepackage{forest}
