Signals Notebook: How to add more than 500 items to an attribute list

Signals currently have a limit of 500 visible attributes within the attribute list if the User Interface (UI) is used to view these attributes. This limit is documented in the following article Signals Notebook: Explore the limits of Signals Notebook.  Once a list of attributes exceeds 500 values, it will not be possible to view elements of the attribute list or add new values thru the UI. 

A way to add elements to this list of attributes is by using Signals Notebook's Swagger, specifically the endpoint Attributes -> Patch/Attributes/{eid}/options. This endpoint will allow you to add new options to the attribute list. Below you will find an example of a Request Body for adding new values using Signals' swagger.

{
  "data": [
    {
      "type": "option",
      "attributes": {
        "action": "create",
        "value": "NEW ATTRIBUTE NAME HERE"
      }
    }
  ]
}
