How to duplicate multiple mod elements

Im working on a mod that adds multiple blocks (with same functionality) just diffirent variables. I already made 1 fully functional block and now 1 need to copy all it features 10 times, but i quicky found that i can only copy 1 mod element at a time. Can somebody tell me how can i copy multiple elements at a time or take a different approach to how the block and its functionality is made so i dont need to copy it
