Aggregate Visualization in Workspaces

I'd like to graph the total page views for a section of my site. When I use the filter on Page, I get the stats for each page by month and if I graph it, it's a graph for each page. Above the filter is a sum of total page views for my entire site, but no total for just the filtered pages. How do I get an aggregate number for just my filtered pages? I suppose I could do it by creating a segment, but that feels like I'm cluttering up my segments for a very temporary purpose (and I can only create a temporary segment based on a specific selection, not a filter).
