I wish AnimBP can edit like template

if I need many AnimBP used same or similar AnimGraph Logic, but used diffrent Skeleton and diffrent Anim Asset.the bone name is diffrent too. Just copy AnimBP is bad because if I edited one AnimBP, another did not update. AnimBP is not like programming language. And it is more like a program that we use in a fixed way.And if I need use c++ to code AnimGraph. I can`t find any document.
