Replace Prometheus' external-url with query by Grafana explorer url

I have:

Data source for Alertmanager added to Grafana
Now I see alerts from Alertmanager via URL: /alerting/groups?alertmanager=Alertmanager
but each active alert has Source field from Prometheus, in the same time via URL: /alerting/list without any plugins I see Grafana explore link to see graph in Grafana.
How I can do the same thing for Alertmanager?
Is there any way to replace “See source” value by link to Grafana explore with the same query?
