[Feature]: multipart accepting form data

[NikkTod]

🚀 Feature Request

Hello,

Use case:
Back-end Glue API service accepts multiple files with same field name 'attachment'

POST https://host:post/v1/email

--WebAppBoundary
Content-Disposition: form-data; name="email"; Content-Type: application/json

--WebAppBoundary
Content-Disposition: form-data; name="attachment"; filename="file1.pdf" Content-Type: application/octet-stream

--WebAppBoundary
Content-Disposition: form-data; name="attachment"; filename="file2.csv" Content-Type: application/octet-stream

Trying to send multiple files with following code, but multipart does not accept form data:

const formData = new FormData();
formData.append('email', {Json Payload});
formData.append('attachment', fs.createReadStream('file1.pdf'));
formData.append('attachment', fs.createReadStream('file2.csv'));

response = await request.post("https://host:post/v1/email", {
headers: setToken(),
multipart: formData
});

I saw Java language port supports that, but what about JS/TS ?

Example

No response

Motivation

Supporting multiple file attachments (email API) when that API accepts form fields with the same name.

Looks like a duplicate of #28070

Yep, looks similar, is there some workaround 🙏

Unfortunately not as of today. Folding into it by that.
