Sql Server Server Group query Scenario

I have 4 front-end sql server.

All of them have the same db instances. Data are replicated from back-end databases.

Issue

In SQL Management Studio I have registered the servers and I have created a group (called front_end). The group can be inquired using the sql editor opening a connection to the servers group.

Is it possible to inquire the group programmatically setting the USE clause?

E.g.:

    use [front-end]..myDatabaseInstance
    select * from myTable
If you right click the registered servers group and select "New Query" you get a query window that connects to all the servers, whatever you execute will run on all and return combined results.

If you want to programatically do it, you can use a central management server and query that for a list of servers, and use linked servers to run the query at each location using openquery
