Raygun Feature Request

I'm thinking something similar to the new starring feature, but instead of picking fields to show up in the summary, you would pick fields to aggregate into an overall summary for a set of error occurrences. For example, we host hundreds of customers on our software and very often we have errors with many occurrences, but it is very difficult scanning through all the occurrences to get an idea of how many customers may be affected and other key pieces of information. But if each error report had the ability of aggregating key information among the occurrences, it would be SO much easier to gauge the affect of an issue at a glance.
