Live traffic, group by user agent?

Hi,
is there any reason why we can’t group live traffic by user agent? I miss this option so hard. When I am analyzing traffic to create some blocking rules, I always have a lot of cases where some bot visit-spam the site from different IP addresses but the same user agent. Right now it gives quite a lot work to find those the most problematic ones, because existing grouping options are useless for these cases.

May I suggest this feature or is it no go?
