Remove Specify Amount in payment for Hub Orders.

We can't use the business Hub to create invoices until the 'Specify Amount' in the PAY NOW window is removed. It allows our customers to part part and assume that the order is in production. Causes a ton of issues with our workflow. 

You would think specifying Terms in the system where 100% deposit is required would automatically remove the 'Specify Amount' field at payment. But it does not.

This is a show stopper for us and no doubt many shops that no longer take deposits for orders.
