Is there any alternative for Cloudposse label?

Hi,
I have CloudWatch alerts configured for ELBs. Unfortunately alerts name have random ELBs names inherited which looks ugly:

resource "aws_cloudwatch_metric_alarm" "elb-5xx-backend-anomaly" {
  count               = length(var.monitored-elb-ids)
  alarm_name          = join("", ["ELB 5xx BACKEND errors high - ", var.monitored-elb-ids[count.index]])
  comparison_operator = "LessThanLowerOrGreaterThanUpperThreshold"
  evaluation_periods  = "1"
  threshold_metric_id = "e1"
  alarm_description = "description"
  treat_missing_data = "notBreaching"
  alarm_actions       = [element(var.sns-topics.*.topic-id, 1)]
  ok_actions          = [element(var.sns-topics.*.topic-id, 1)]

  metric_query {
    id                 = "e1"
    expression         = "ANOMALY_DETECTION_BAND(m1, 1)"
    label              = "HTTPCode_Backend_5XX (expected)"
    return_data        = "true"
  }

  metric_query {
    id          = "m1"
    return_data = "true"
    metric {
      metric_name = "HTTPCode_Backend_5XX"
      namespace   = "AWS/ELB"
      period      = "60"
      stat        = "Sum"
      unit        = "Count"

      dimensions = {
        LoadBalancerName = var.monitored-elb-ids[count.index]
      }
    }
  }
}

so that creates an alert like:

module.cloudwatch-load-balancer-alerts.aws_cloudwatch_metric_alarm.elb-5xx-anomaly[0]: Creating...
module.cloudwatch-load-balancer-alerts.aws_cloudwatch_metric_alarm.elb-5xx-anomaly[0]: Creation complete after 0s [id=ELB 5xx errors high - a2e088xxxxxxxxxxxxxxxxxxxxxxxxxxxx]

I found Cloudposse label module but that looks massively over complicated and seems that it needs creating module for each load balancer. Is there any easier way of doing that?
