Similar Customer Name Error

I have 2 customers with the same exact name but I can’t add both of them in ERPNext v14 as it consider the name is the customer ID and can’t be duplicated!
I tried to modify the Doctype to make it as a series naming C-.##### but an error appears:
DocTypes can not be modified, please use Customize Form instead

I need a way to customize the customer ID as it can’t be the customer name, specially when dealing with individual customers!
