Advice on where to look. Related To Search: Account Name:Account Number

Hi. :unsure:

All our Accounts have a number as well as an account name. The Account Number is a custom field within Accounts.

When I am in other modules and click on related to: Accounts and type in the beginning of the name of an account to do a search we could have 10 results with the same name, but they would all have different Account Numbers. Is there a way to Customise this and if so where would I start looking at what module to tweak? to do this so Instead of me typing in Smith. Then getting a list of Smith, Smith, Smith, Smith etc… I’d get Smith:1, Smith:256, Smith:1023 etc… So the Company name and their account number.
