Using CustomizedMetricSpecification for auto-scaling

[SlavkaOnline]

Does exist the ability to use CustomizedMetricSpecification for auto-scaling now? I can't find an example in docs.
Like here
{ "TargetValue":30.0, "ScaleOutCooldown":120, "ScaleInCooldown":120, "CustomizedMetricSpecification":{ "MetricName":"rate_messages_produced_average_1m", "Namespace":"ECS/CloudWatch/Custom", "Dimensions":[ { "Name":"ClusterName", "Value":"ecs-sarathy-cluster" }, { "Name":"TaskGroup", "Value":"service:PublisherService" } ], "Statistic":"Average" }

Hi @SlavkaOnline !

Today, Copilot doesn't expose a way of using custom metrics for autoscaling. The feature request makes sense to me, we'll keep it open and post updates as the work gets picked up.
