Would be wonderful to have the layer a fixture is in as a piece of data for Reports. On a massive show now, and a lot of the same fixture types have different purposes and different layers, and it would be a great way to keep track during a massive patch.
If you right click on the report title in the left column you can set the Scene that report is using (rather then using all layers). This could help you to organise your rig. You need to copy the report for all your locations to include all your fixtures
