Using docsify-select to do profiling for a whole page

Is your feature request related to a problem? Please describe.
We often have the issue that we need to maintain the same documentation for different target groups. The differences for them are minimal. We would like to maintain these differences once, and reuse the rest of the markdown text.

docsify-select is a plug-in that seems to offer this, but we'd have to duplicate the whole markdown text, and double maintain them.

Describe the solution you'd like
I'd like to be able to define the list box entries once for a complete markdown page, for example, "internal" and "default", and then be able to use a syntax in the markdown file to mark the beginning and the end of such sections, for example:

# Bake a cake

## What you need

1. Flour.
1. Sugar.
~~start:internal~~
1. Secret ingredient.
~~end:internal~~
1. Eggs.

For "default" all sections marked with start:**** / end:**** should be hidden.

Describe alternatives you've considered
I checked on docsify-mustache, but it seems it can only print out the values of variables, but cannot evaluate them to hide text snippets.

If you know if any alternatives to use profiling with docsify, it would be great if you could point me to them.

Start by reviewing the existing docsify-select implementation and its documented selection behavior, then compare the referenced docsify-mustache alternative. Define how one page-wide list of profiles and the proposed start/end markers should be parsed, including the default view; done means marked sections render only for their selected profile without duplicating the surrounding markdown.
