Nickname for 1099-R entries (and other income sources)

It would make my data entry much more straightforward if I were able to assign a nickname to my 1099 forms.  I have many coming from the same providers but for different accounts or taxpayers (my wife, as we file jointly).  Instead, I have to use the Payer name exactly as from the 1099 form, making the list of imported 1099s look all the same, and thus difficult to navigate.  Why can't TurboTax support a nickname field for income sources such as 1099s?
