Update Item Checkbox Feature Request

Currently: Add existing item to invoice, edit description and/or price > save or send. Go to next invoice and add item and the item now has the changes made to the item in the last invoice. However, those changes may have been discounted for some reason.

Feature Request: add check box in first column before the item "Change Item" so if checked it will affect the Item beyond the particular invoice otherwise the edit is only for that current invoice.
