Can't create alert rules for specific monitors anymore [8.13.4]

Hello,
in the past I used to create separate alert rules for some of the Uptime or Synthetics Monitors to use different connectors for alerting (e.g. different Slack Channels).
I noticed today that with the current version, there's only one synthetics alerting rule and one TLS alerting rule and no option to create a new alerting rule of the type " Synthetics monitor status" or "Uptime" anymore. I tried to modify the existing synthetics alerting rule to use a different connector depending on a KQL Query. I tried referencing the monitor uuid or tags used on the monitor but these fields aren't available for the filter.
How can I achieve certain monitors alerting using specific connectors then?

I'm using 8.13.4 for the Elasticsearch Cluster, Kibana and Fleet Server.

Hi @chmaeuer,

Thanks for using the Synthetics monitoring solution. The Synthetics alerting functionality is not configurable atm, but its being worked on to make it more configurable.
