Support multi-binary cortex mode in grafana alerting

What Grafana version and what operating system are you using? : v8.0.6

What are you trying to achieve?: Trying to configure cortex metrics alerts using grafana new unified alerting way.

What happened: We are using the multi binary deployment of the cortex and looks like the grafana will not support multi binary cortex deployment for alerting. We need to understand how can we achieve this using grafana?

Is there any way to achieve the alerting of multi-binary deployment of the cortex using grafan?
