User Roles/Privilages

It seems that there are no ways to customize the 3 predefined User Roles given in Zoho Books?
This is a real turn off for our company. There are employees who are not suppose to see account balances and expense reports, but need to be able to create estimate and send invoices and check contacts.

When will Zoho Books users will be able to do that?
