It appears that I cannot combine luminaires into groups and then change their Tilt, Roll, or Spin. I can only adjust the orientation.
I often deal with decorative fixtures including linear fixtures at various lengths.
Right now I have a linear section made of multiple 1ft sections that I want to place running up the side of two walls and across the ceiling. All I can do at the moment is take each 1ft section and rotate it appropriately by itself and then copy the next segment 1ft above that. It would be much easier to create the run length and then tilt/roll/spin it and then adjust the mount height.
