Edit or Add Customer Information in New Invoice Screen

Currently, if you start a new invoice from the New Invoice tab you are unable to add or edit information to an existing customer's file from that screen. There should be an EDIT button alongside the NEW and PICK buttons that would allow you to go directly to a customer's file to update or add information such as email address. If you start in the CUSTOMERS tab from the Home page, you can create a new invoice and later push the back button to get to customer's file. Adding and EDIT button above Customer in the Invoice screen would allow you to directly go to their file regardless of how you got there. (Apple IOS)
