I am having trouble getting a bottom bolt to show correctly when adding a C-Clamp using the Lighting Accessory Tool in 2021. It seems that everything with the record containing Base is always attached to the light above the Yoke - although traditionally, there would always be a bolt below the yoke that screws into the C-Clamp. Anyone have any clue how to create an C-Clamp Lighting Accessory that has a bolt below?
