Currently, the following Page URLs/Page title segments are supported:
Actions exitPageUrl Exit Page URL exitPageTitle Exit Page Title entryPageTitle Entry Page title entryPageUrl Entry Page URL
It could be useful to also support a segment that selects all visits that visited a given Page URL/Page Title during their visit.
For example, "Give me the top Keywords widgets for all visits who looked at the purchase page"
