Duplicate Module Leads for Module Account

Hi there,

My SuiteCrm is 788 and I made some changes. Because I have to work with Customers and Courriers I changed tha Strings “Accounts” and “Contacts” on the Language Pack to “Courier” and “Accounts”. Now I can import my List of Customers into Targets -> Leads -> Accounts. I want to duplicate the module Leads so I can do the same for Contacts Module eg. convert Leads -> Contacts.

Could someone please tell me the file I need to consider, how to do it and which code I have to change?
