Want to change All clone forms at a time

Dear Sir
I have 3 clones of the same form. I am using it for 3 different regions. Is there any mechanism in which if I change/edit in one form, it goes to all at a time. Otherwise, I have to the same edit in all forms, which is cumbersome.

3 cloned projects means 3 different projects. Hence kindly please be informed that making change to a cloned project would not bring change to the other 2 cloned projects. You would have to make changes to the rest of your projects manually.
