In my case, we work with companies who have several locations, in my company we have always considered each of our accounts compound by "Group and plant", for instance, the GROUP YAZAKI, may have plants, I am looking to implement some similar organization in which my accounts can be organized as follows:

- Yazaki

      - Europe

            - Ovar

            - Barcelona

            - Ploiesti

      - Asia

            - Tokyo

            - Shanghai

how could I implement that?
