renaming master and node names

Hi

Is it possible to have a command line argument that can prefix the master node names and worker node names to something different?

For example, lets say I am using StarCluster to start a cluster of 3, right now it has the names as master, node001, node002. Is it possible here to have the names as prefix_master, prefix_node001, prefix_node002 

Thanks in advance,
Anand
