Listview as parameter

It would be very handy to pass a listview as a parameter, more specific as a list in a microflow. Because now I have to add a boolean “selected” to the entity and a corresponding checkbox in the listview. Then I need to retrieve from that entity everything with “selected = true”, etc… It wou be so much faster (Mendix Strong Point nr 1!!!), if we could just use the objects in the listview as a list-parameter.
