Copying Existing General Ledger Business Unit

Is there a way to copy an existing business unit (GL) to create a new GL business unit that will have all the setup mirror the copied unit for both the General Ledger Definition, Ledger for a Unit and TableSet sharing?

I am in the need of setting up over 20 new business units manually keying all the data individual is a bit cumbersome.

Or is there any other user that might have used Excel to CI's, or some other method to create numerous business units at once?

Any assistance and suggestion will be gladly accepted.
