[Question] Quicker Way to line cleanup

Hey so i do anaimtions with shape tweens and then merge the layers so theyre one thing that i can fill in with the bucket. However when i do the tweens theres alot of line overlap on the differnt layers. To fix this i FBF it and just go through erasing the line cleanup but im wondering if theres a quciker way to do this or if this is the quickest way
