Add feature to view multiple blocks in the RayCloud

I believe that figure 5 in the quality report tries to answer that but it is really not convenient. There should be a feature directly in the rayCloud to visualize where and the blocks and what camera belongs to which block and where they are. I saw on the forum someone suggesting different colors which I think would be enough but the option to have one block in one layer to turn it on/off easily would be also great.
