Using Field Type Dropdown (Multi-Select Searchable List)

I see the "Dropdown (Multi-Select Searchable List)" field type is not included in the list of supported field types on this page: https://developer.icims.com/REST-API/Object-Types-Commands/Field-Types

That said, we have successfully made GET calls to retrieve data from the Dropdown (Multi-Select Searchable List) field type. A sample response is below for the GET with obfuscated ID's & values.

{
"links": [
{
"rel": "self",
"title": "The current profile being viewed.",
"url": "https://api.icims.com/customers/{custmerID}/jobs/{jobID}"
}
],
"field675696": [
{
"id": "C676XXX",
"formattedvalue": "{formattedvalue}",
"value": "{value}"
}
]
}

The question is: is there a way to POST or PATCH into a field with the type of Dropdown (Multi-Select Searchable List)? Our hope is the field type has become supported since the field type page was last updated since the GET works. If so, could you share how to successfully make a POST or PATCH using the Dropdown (Multi-Select Searchable List) field?
