Queue performance Activity report by period of time

This report could be far more useful to identify trends, if the report allowed to view data from several dates.

For instance, as this works right now, there's no way to quickly know which hours of the day are the busiest. We can see which hours were busiest on a specific day, but if I could select a range of dates (say, the last 3 months) and get the same report I could have a pretty good idea of which times get the most calls.
