How about a host name? You could make it easy to match with a class, like:

well-done-host-00123
well-done-host-00124
well-done-host-00125

Then match on substring of host name excluding the serial.

Possibly using some HW part e.g. MAC or part of MAC for the number part.
I think there might be a hook for something like this. Others will know
better.
