I need to have all html headlines on text on a webpage to have distinct IDs – Is it possible to rewrite the markdown parsing in a plugin in order to achieve this:

```markdown
## Headline

```

becomes

```auto
<h2 id="headline">Headline</h2>

```

or do I need to use a custom kirbytag?

If you can’t rely on unique headlines, you could add a unique hash…
