Is it possible to use Odata API to upload an attachment directly to a specific PM form?

SAP SuccessFactors Performance Management

Below is a standard way to upload a single attachment to the PM domain. 
Note: File content is required. The default size limit is 5M. In the payload, the file content is displayed as a base64-encoded string. 

Request:

    "__metadata": {
        "uri": "Attachment"
    },
    "userId": "cgrant",
    "fileName": "f1.jpg",
    "description": "des1",
    "fileContent": "ZHV6aWVsZQ==",
    "viewable": true,
    "deletable": false,
    "moduleCategory": "PERFORMANCE_ASSESSMENTS",
    "module": "PERFORMANCE_MANAGER"

Response:

{
    "d": {
        "__metadata": {
            "uri": "https://<API-Server>/odata/v2/Attachment(8106L)",
            "type": "SFOData.Attachment"
        },
        "userId": "cgrant",
        "fileName": "f1.jpg",
        "description": "des1",
        "fileContent": "ZHV6aWVsZQ==\r\n",
        "viewable": true,
        "deletable": false,
        "moduleCategory": "PERFORMANCE_ASSESSMENTS",
        "module": "PERFORMANCE_MANAGER",
        "attachmentId": "8106"
    }
}

By giving values to the module and moduleCategory fields, you can upload an attachment to a specific SAP SuccessFactors domain.
However, when you upload an attachment to Performance Management, it isn’t associated with any forms.
In the above payload, you can notice that there are no properties indicating which form the attachment will be uploaded to. That means you can't use Odata API to upload an attachment directly to a specific Performance Management form.
