Ability to point in interface that value should be treated as element of array

[w1zdun]

In below code generated from tool, "eventName" and "eventSource" attributes should be arrays in the same way as "source" and "detailType":

 new events.Rule(this, "Event_r53dump", {
      eventPattern: {
        detail: {
          eventName: "ChangeResourceRecordSets",
          eventSource: "route53.amazonaws.com",
        },
        detailType: ["AWS API Call via CloudTrail"],
        source: ["aws.route53"],
      },
      targets: [new eventsTargets.LambdaFunction(r53dump)],
    });

It will be great to have ability to influence code generation behavior to add square brackets.
