Triggering goals processing

I am using Piwik to get analytics of the website usage. I am using apache log files to populate the data.

I am playing around with goals to track various user behavior.
In my so far experiments, I concluded that goal analytics only when the new logs are imported. So I do not get the goals analytics for log file imported so far.

Is there any way, so that I can tell piwik to trigger the goal anlytics to be regenerated again, based on accumulated data.

Thanks and Regards,

Goal tracking is only for new data. We could implement a “backward goal tracking” but we havent yet and it’s not in our priorities yet
