frontmatters scoped path

Feature request

What problem does this feature solve?

With these settings:

frontmatters: [
  {
    // Unique ID of current classification
    id: 'tag',
    // Decide that the frontmatter keys will be grouped under this classification
    keys: ['tag', 'tags'],
    // Path of the `entry page` (or `list page`)
    path: '/tag/',
    frontmatter: { title: 'Tag' },
    layout: 'BlogTagsLayout',
    // Layout of the `scope page`
    scopeLayout: 'BlogTagLayout'
  },
  {
    // Unique ID of current classification
    id: 'en_tag',
    // Decide that the frontmatter keys will be grouped under this classification
    keys: ['tag', 'tags'],
    // Path of the `entry page` (or `list page`)
    path: '/en/tag/',
    frontmatter: { title: 'Tag' },
    layout: 'BlogTagsLayout',
    // Layout of the `scope page`
    scopeLayout: 'BlogTagLayout'
  }
]

I got:

[@vuepress/plugin-blog] ====== Automatically Added Index Pages ======

/tag/                   {"pid":"tag","id":"tag"}                                      {"layout":"BlogTagsLayout","title":"Tag"}

Expected:

...
/en/tag/vuepress/       {"pid":"en_tag","id":"vuepress"}       en_tag  vuepress       {"layout":"BlogTagLayout","title":"vuepress en_tag"}
/en/tag/vuepress-blog/  {"pid":"en_tag","id":"vuepress-blog"}  en_tag  vuepress-blog  {"layout":"BlogTagLayout","title":"vuepress-blog en_tag"}
/en/tag/js/             {"pid":"en_tag","id":"js"}             en_tag  js             {"layout":"BlogTagLayout","title":"js en_tag"}

What does the proposed API look like?

Like Dynamic Route Matching.

How should this be implemented in your opinion?

How about modifying these lines:

Are you willing to work on this yourself?

I want to if I can...
