Does Cash Management store the GL Book Balance - R12

Hello All:

Given the following situation. The client has 10 bank account linked to 10 GL accounts. In R12 cash management you can configure 10 bank accounts to the one GL control account.

However in the cash management do you have access to the GL book balance. In other words does Cash Management store the bank balance as per GL.

Thanks in Adavnce
