Thanks - I have no problem erasing history rather than modifying it.

Another example of where I'd like to do this is where I was doing some 
experiments with different test durations - e.g. 5 seconds, 7 seconds, 
10 seconds. Now I have separate esmond archives for each set of 
parameters, and this makes navigating the JSON rather painful.
