How can we improve WHMCS?

There is no ability to select the required documents on a per client basis. For example, let's say an order type is PayPal but we wanted to request verification from the end-user, but on the global settings (within /admin/configfraud.php) we select credit card under the required documents section, it would still request a picture of the credit card from the end-user performing the verification. That being said, within the order page in the WHMCS admin panel, there should be an option to select what required documents an admin would like to request from an end-user on a per order/client basis, rather than a global basis.
