Banking: Ability to turn off auto allocation

There really needs to be a setting to turn off auto allocation.  Its a pain in the butt. Granted sometimes it works but the amount of times it auto allocates the wrong payment to something, usually a supplier invoice, and then we have suppliers ringing and complaining that an account hasnt been paid as it has been cleared from the supplier invoices due to the wrong allocation.  It really is a hassle and I would much prefer to manually allocate all transactions myself.
