How can I hide proforma invoices under the accounting module to a specific group/user? I'm trying to hide the records that show when you click Customer Invoices (Under Accounting > Sales > Customer Invoices) if it's in the proforma state.

For example: The business manager would see the following:

CUSTOMER | STATUS

Customer1 | Open

Customer 2 | Pro-forma

Customer 3 | Paid

and the user would see

CUSTOMER | STATUS

Customer1 | Open

Customer 3 | Paid

This is for Odoo 10.0 under the Accounting/Invoice module.
