Great Suggestion.  This is what we do (in Excel) with a number of our reports to squelch out the noise produced by low trafficked pages or terms.  This functionality would allow us to use omniture dashboards for reports on searches or pages with the highest and lowest bounce rates, conversion rates,...

We currently restrict log-in to local IPs only.  While we want to enforce that restriction for the majority of users, there is a subset of users who should be able to login to omniture from various locations.  It would be helpful to allow or restrict non-local access based on group membership.
