It would be great to get the ability to group several visuals to set only one visual filter for all visuals you want.
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 each single visual with an own visual filter (e.g. 10 times the same filter) because the site filter and the report filter would filter all visuals by the same settings.
