Thanks for comments, I already have some idea how to do it.
But, there is another doubt:
1. I am a LL of GCC
2. We have few sub-circles
3. I want to create some rule related to payment/cost approval.
4. There are some roles in a sub-circle, that have special meaning in our cost approval (i.e. raw material purchasing)
My question is: As a LL of GCC, can I grant some permission to the role that exist in a sub-circle? (from the point of view of constitution, as well as common sense..)
