"publicUrl": "../" is proper?

Nice to meet you🙏
Please let me ask about the usage of "publicUrl" with relative path.
For example, I have two html files as entry points(doc1.html, doc2.html) and both files refer same image file(image1.jpg).

- src
    - images
        - image1.jpg
    - sub
        - doc2.html
    - doc1.html

When I want resolved path not to be absolute but relative, is this targets field in package.json proper?

{
  "targets": {
    "doc1": {
      "source": "src/doc1.html",
      "publicUrl": "./"
    },
    "doc2": {
      "source": "src/sub/doc2.html",
      "publicUrl": "../"
    }
  }
}

It seems to work apparently well. But resolved url of shared resouces like image1.jpg in example is broken. I can't distinguish whether it's a bug or an improper configuration.

I'm sorry. Maybe I'd misunderstood the purpose of "targets" field. I realize parcel buid outputs same resouces for each targets. I'll start over reading docs. Forgive me for my confusion.
