Hi,
The following SWG feature can help:
SWG consolidates the reports by default after 0 days so, different entries from the same computer to the same domain name will be displayed as a single report entry. The administrator can postpone this consolidation for up to 28 days and maintain visibility of all the different URLs within a given domain by accessing Administration -> Configuration -> Modules and changing the number of days under:
Consolidation - Disable report consolidation of Content Filter events for the first 0 days
This will of course increase the database usage.
