Create "replicate attribute" option to schema definitions about dynamodb-toolbox HOT 4 OPEN

Is there a way as it stands right now to make the partition key be duplicated to the sort key? Given the array notation for defining sort keys, I don't see how that is possible. I attempted to alias the pk with id, and then define id in the schema as ["sk", 0] but then the alias isn't unique and I get the associated error for that scenario.

Edit: Would it be possible to use a default provider here that has access to what the pk is set to?

Edit 2: So far the solution I have is the following. Do you know of a better solution?

// Schema
const Record = new Model("Record", {
  table: "TestRecordTable",
  partitionKey: "partitionKey",
  sortKey: "sortKey",
  schema: {
    partitionKey: {type: "string", alias: "id"},
    sortKey: {type: "string", hidden: false},
    sk: ["sortKey", 0],
    pk: ["partitionKey", 0]
  }
);

// DB Operation
const id = `record#${uuid.v4()}`;
const item = {
  pk: id,
  sk: id
};

The easiest thing would probably be to use default instead.

// Schema
const Record = new Model("Record", {
  table: "TestRecordTable",
  partitionKey: "partitionKey",
  sortKey: "sortKey",
  schema: {
    partitionKey: {type: "string", alias: "id"},
    sortKey: {type: "string", onUpdate: true, default: (f) => f.partitionKey }
  }
);

I'm working on a better way to do this.

Unfortunately this doesn't work if the partition key also has a default provider. Although your solution does reduce that amount of data that I have to provide to the Record.put() call.

+1 to this feature, I have to duplicate values quite a bit for GSIs, and setting the default over and over is a bit annoying
