Can I set AlertManager repeat_interval for a specific receiver/alert?

We are using Prometheus to send alerts. We have a global repeat_interval route of 10 hours as default, but I would like to up this to 200 hours for a specific receiver/type of alert.

I have already upped the --data.retention to 200 hours (as it defaults to 120h), but I don't want to change the default repeat_interval, only for a specified receiver.

This is my alertmanager.yml:

global:
  resolve_timeout: 5m

route:
  repeat_interval: 10h

  routes:
    - match:
        severity: 'critical' 
        receiver: 'email' 
        continue: true

receivers:
  - name: 'email'
    email_configs:
      - to: "my@email.com" 
        from: "{{from}}" 
        ...
        headers: 
          subject: "SUBJECT"

  - (other receivers...)

I would want to set the repeat_interval of email-receivers to 200h, but keep the default route-repeat_interval to 10h. Is this possible?

Use the following:

route:
  repeat_interval: 10h

  routes:
    - match:
        severity: 'critical' 
      receiver: 'email' 
      repeat_interval: 200h
      continue: true
