How can I do an overwrite, to specify a file for a binary?

[wernermorgenstern]

I am trying to do an search/replace, to specify a filename, so that I can run postman-to-k6.

I tried using the portmanReplacements, but it is not letting me use the double-quote in the searchFor string.
I tried using the overwrites for the overwriteRequestBody, but it seems to only work for JSON, form-data, and Form url encoded values.

How can do an overwrite on a binary or application/octet-stream?

Here is my OpenAPI Spec:

components:
  parameters:
    fid:
      name: fid
      in: path
      description: File ID
      required: true
      schema:
        type: string
        pattern: \w+\.\w+
        minLength: 4
        maxLength: 24

paths:
  /files/{fid}:
    put:
      summary: Upload File
      operationId: uploadFile
      tags:
        - Files
      parameters:
        - $ref: "#/components/parameters/fid"
      requestBody:
        required: true
        content:
          application/octet-stream:
            schema:
              type: string
              format: binary
          image/jpeg:
            schema:
              type: string
              format: binary
          image/png:
            schema:
              type: string
              format: binary
      responses:
        "201":
          $ref: "#/components/responses/UploadFile"
        "400":
          $ref: "#/components/responses/BadRequest"
        "401":
          $ref: "#/components/responses/Forbidden"
        "403":
          $ref: "#/components/responses/NotAuthorised"
        "404":
          $ref: "#/components/responses/NotFound"
        "406":
          $ref: "#/components/responses/NotAcceptable"
        "415":
          $ref: "#/components/responses/UnsupportedType"
        "429":
          $ref: "#/components/responses/TooManyRequests"
        default:
          $ref: "#/components/responses/GeneralError"

And here is what I get currently:

            "header": [
              {
                "key": "Content-Type",
                "value": "application/octet-stream"
              },
              {
                "key": "Accept",
                "value": "application/json"
              }
            ],
            "method": "PUT",
            "body": {
              "mode": "file"
            }

And I want it to look this way:

                        "header": [
              {
                "key": "Content-Type",
                "value": "application/octet-stream"
              },
              {
                "key": "Accept",
                "value": "application/json"
              }
            ],
            "method": "PUT",
            "body": {
              "mode": "file",
              "file": {
              "src": "FILE_LOCATION"
              }
            }
