Copy GL accounts

In JDE Enterprise One v9.0, how do I add a new GL account. All I want to do is take an existing GL account, change the subsidiary to create a new account. I've tried going to Revise Single Account - Work with Accounts and Adding and then changing the sub but I get the warning about doing the global update and that's not what I want. I want to leave the account information in the old account, I just want a new account with the same set up but a different sub at the end.
