Ability to suspend partial payments on a per customer basisension

Feature requested
The ability (easiest via a tickbox on the client control options page) to suspend the partial payment ability of a particular customer.

Typical use case
Quickfile allows partial payments but only as a ‘one size fits all’ and it should be possible to remove the option for abusers of the facility without penalising all other customers/clients.

How I would expect it to work
If the suggested simple tickbox placed on the client controls option page is enabled then when an invoice is generated the tickbox is checked and if active the option to alter the amount is removed.

Most of the logic must already be in place as you have the option not to enable for all.

Thank you.
