As said above it would not be worth the effort in doing it. When shooting a rifle out to a hundred yards, you can be way off and miss target completely and is helpful with this and is beneficial when considering the cost of ammo. But if you put a scope on and can not hit a 2'*2' target at five to ten yards then you may have big problems. Plus you reuse your arrows so its not like it cost you ammo. Not worth the work IMO.
