Generate single Embed Token for multiple reports?

[Anonymous]

The documentation tends to suggest it's possible to generate an embed token for multiple reports https://docs.microsoft.com/en-us/rest/api/power-bi/embedtoken/generatetoken

I'm passing a list of reports in the POST payload as follows:

{
  "reports": [
    {
      "allowEdit": false,
      "id": "077fd657-6ba6-473e-9e55-570a84e95ef4"
    },
    {
      "allowEdit": false,
      "id": "077fd657-6gf6-473e-9e55-570a84e95ef4"
    }
  ]
}

When I submit the request I receive an error:

{
    "error": {
        "code": "InvalidRequest",
        "message": "At least one dataset is required"
    }
}

I don't want to do any kind of dynamic binding, I just want to generate a single embed token that can display multiple reports. Is there any way of doing this without having to specify the dataset for each report?
