Universal slicer?

I assume its not possible, since I've exhaustively looked for a way to do it, but I have 3 pages of data and, ideally, I would like for a single slicer to filter the controls on all 3 pages instead of just the page it's on. For example, when someone filters for a specific salesperson on Page 1, then clicks over to the data on Page 2, there is no filter applied to the Page 2 data. So I have to duplicate the slicers on each page and the user has to re-apply the filtering to the new page every time he/she switches to a different page. Am I missing something or is this just The Way It Is? Any chance slicers of the future could be made to apply to all elements on all pages instead of just those visible on the same page as the slicer in question? Thanks
