Is it possible to add an attribute to a collection so the generated schema has the "uniqueItems" property set?

From this:

[UniqueItems]
public List<string> UniqueStrings { get; set; }

Or

public HashSet<string> UniqueStrings { get; set; }

To this

"UniqueStrings ": {
      "type": "array",
      "uniqueItems": true,
      "items": {
        "type": "string"
        ]
      }

Other ideas and workarounds are welcome, too!
