How can I change trusses that are full of fixtures to a different brand with the same length? Or how do I change e.g. 2 x 5 meter pieces of truss with 4 x 2,5 meter pieces of truss? It seems that the only way to do this is to draw the new truss next to the old one and drag each fixture over, delete the old truss and move the new truss to the old position. This seems quite a bit of work. Maybe there could be a function like change fixtures?
