Forward alerts from one alertmanager to another alertmanager

I’m stuck in how to forward alerts from one alertmanager to another alertmanager.

Looks like the alertmanager doesn’t provide the interface to forward alerts, the only way I can figure out is using the Alertmanager webhook receiver, I have to write my own webhook server to receive alerts from the source alertmanager and then forward the alerts to the target alertmanager, does it make sense?

Any insight? Appreciate it if anyone can help on this.

I didn't found any proof that Alertmanager supports this feature, so I write an Alerts-Collector(https://github.com/morvencao/alerts-collector)  that implements a webhook server to receive alerts from downstream Alertmanager and performs an alert forward to upstream Alertmanager instances.
