Hi,
You can set up each Adobe Analytics reportlet to have a single line item URL filter or overall segment(s) filter, but it must be designated in advance within the reportlet. At this time there is not a way to have variable single URL search filters that then would apply depending on viewing user choice or some type of dynamic lookup.
If you built a dashboard using the Excel Report Builder Add In that would potentially allow you to perform more dynamic filter and search functions.
Best,
Brian
