How to query the Application Loadbalancer associated with a Target Group in Grafana template?

#1

I am setting up a dashboard in Grafana that would take data from Cloudwatch and show metrics related to TargetGroups. Most of the metrics need the loadbalancer as a dimension as well. How to query the loadbalancer name if I have the Target Group name?

For templating, I am getting the available loadbalancers with a query. This is giving all the loadbalancer names and that is not very helpful for the user

This is giving all the loadbalancer names.

dimension_values($region,AWS/ApplicationELB,HealthyHostCount,TargetGroup) 

Is there any filter or another method to only get the loadbalancers associated with the specific Target Group I have?
