Creating sub-accounts to a standard account

Creating sub-accounts to a standard account

I am new to Zoho Books and currently I am preparing the Chart Of Accounts for my organization.

I wonder if we can create sub-accounts to a standard account in Chart Of Accounts and do simple addition calculation to these account? For example, A and B are sub-accounts of C account. Therefore, the total sum of A and B is the number displayed in C account.

Thank you for helping me.
