Dynamic Component Question multi-animation simular components

Although attached stair steps animates properly.. I wonder if there is an easier way to trigger all the steps instead of copying the animate behavior and adjusting the step-number. Anyone? Would appreciate a better solution.

itโ€™s easier if you upload your DC, please do. then I can build on it

however, the rotation should be in one tread, then that copied based on stair overall, rise and going.

animate in parent of a referenced angle
