Excluding data on a Visual/Scatter plot should extend as a page/report level filter

For me this is a mandatory feature. I have a page where I show an entire dataset on a scatter chart and users can identify outliers using it. I also show the statistics (mean and std dev) of the dataset on other visuals on the page. I need to have the excluded values affect the statistics so users can estimate the impact of removing those outliers. In an odd way you can get this type of functionality. My data is composed of data from multiple sources (multiple serial numbers), which I use in the Legend well. So if you click on one serial number, all visual on the page get filtered to just that serial number (in the filter pane that serial number is 'included')...good. If you THEN exclude a data point from the serial number's dataset the other visuals exclude that data point as well (that data point shows up in filter pane as excluded and the serial number still shows as included)! So once you have a cross visual filter, via highlighting one of the Legend items, you can exclude data points within that limited subset of data...
