Cross-region Fargate deployment with Codepipeline and code deploy?

[dhhoang]

My use case: I have multiple Fargate cluster stacks which I deployed to several regions.
I want to have use codepipeline cross-region deployment, but I can't seem to get it to work with CDK.
For example, the pipeline created in region-1 has this deployment action

{
  stageName: 'DeployTest',
  actions: [
    new codePipelineActions.EcsDeployAction({
      actionName: 'DeployTest',
      service: ecs.FargateService.fromFargateServiceAttributes(this, 'FargateSvcImport', {
        cluster: ecs.Cluster.fromClusterArn(this, 'FargateClusterImport', 'arn:aws:ecs:<region-2>:<account>:cluster/AppTest'),
        serviceName: 'AppTestSvc',
      }),
      imageFile: new codePipeline.ArtifactPath(buildArtifact, 'imagedefinitions.json')
    })
  ]
}

What I've tried is to have codedeploy references the service from the target region, as mentioned in #11199
This pipeline can be synthesized and deployed, but it result in a deployment step that's in the SAME region as the pipeline (aka region-1)

What I want to happen is for the deployment action to be cross-region

Is there anyway to achieve this?
