Is it possible to create "wildcard" data-sources?

Is it possible to collect common data from multiple hosts? Eg. Ten instances of Prometheus running on ten different hosts. I know I can create ten individual Prometheus data sources and then create ten queries in order to build a summary chart but what I am looking for is a way to automate it so if I created a new host and installed Prometheus I could then automatically create the datasource in Grafana and update the Graph.
Is there some kind of wildcard function e.g. Prometheus.* or a macro language that could either create a new panel per host, or add the new host to an existing panel?

Hi @techietubby,

As far as I know, this is not possible. There are alternate solutions if you need to scale Prometheus that much, I believe
