SAM template - using variables?

I want to create some custom templates to monitor MSMQ message counts, and apply them to multiple servers.  I'm using Performance Counter Monitor and the MSMQ instance names are formatted as SERVER1\queuename, SERVER2\queuename, etc.  Can I use a variable in place of "SERVER1" and "SERVER2" that uses the hostname?  It works fine if I use the explicit instance name, but then I would need to create a "template" for each server and queue I need to monitor.
