Auto Populate Account Info on Potential

Auto Populate Account Info on Potential

We have our Account information set up as follows

Territory      Account Owner      Account Number      Account Name
01                  Jim Smith            123456                        Acme Manufacturing

In Potentials, Account Name is a lookup field so when I click on the icon a list of all the accounts with all of the above information appears. So I click on "Acme," and the account name fills the Account Name field. Since it is important for our Regional Sales Managers to look at territory numbers or account owners, how would I auto populate custom fields Territory and Account Number and the standard Zoho standard field Potential Owner with the account information? I'm trying to avoid our Reps to enter information multiple times.

Thank you,
