Get blocks references if shown in viewport

I want to get the block references if it is shown in the layout viewport (civil 3d). Is this possible? I have not been able to find any node for this?

One way to do so is using the Civil3DToolkit nodes to get the outline of the viewport and transform it to Modelspace (don’t forget to apply the scale and twist). Then find all block references and see if it falls inside the boundary.
