Add a StoryReporter method before starting each individual example

I would like to write a StoryReporter that graphs the run time of each scenario in rrd, e.g. run a use case after login and show how the reponse time varies over time. This should work well with the beforeScenario/afterScenario methods, if the scenarios are executed one (i.e. do not use an examples table).
If a scenario however uses an example table, the individual before/after events are not reported, so the only way to do this is to count the success/failure calls, which looks kind of error-prone to me.

Can we add a beforeExampleScenario method to the StoryReporter ?
