Group Level Filter

When you have, e.g., 10 visuals and you would like to filter the first 5 visuals and the second 5 visuals for different periods, currently the only option is to filter every single visual with its own visual filter (e.g., 10 times the same filter) because the page filter and the report filter would filter all visuals by the same settings.

So, this idea would apply a single filter in the filter pane to all selected visuals in a group, using the "Group" visuals feature. Multi-select -> right click -> Group visuals.
