How to Set Up Multi-Branch Chart of Accounts in ERPNext V15

I need to set up a multi-branch Chart of Accounts (COA) in ERPNext with the following structure:
Company ABC
├── Branch A (Group)
│ ├── Branch A - Assets
│ ├── Branch A - Liabilities
│ ├── Branch A - Income
│ ├── Branch A - Expenses
├── Branch B (Group)
│ ├── Branch B - Assets
│ ├── Branch B - Liabilities
│ ├── Branch B - Income
│ ├── Branch B - Expenses
How can I set this up manually in ERPNext or import it via Excel? Are there any best practices for handling multi-branch financial reporting? Any guidance would be helpful!

how about creating one chart of account and using cost centers for transactions. or create branch as child company
