Rechecking for Correct Volume ID

I know you can use volume names instead of volume IDs in the watch file, but is there a way to have this always look for the volume name? It seems to just map the name to the ID. The problem I'm having is, when spinning up new EC2 instances periodically (i.e., with spot instances), the volume name stays the same, but the ID changes, and then I have to unwatch/watch again.

Thanks,
Mike
