A warning when entering high-dollar patient payment amounts.

It would be nice to have an alert filter for high dollar entries that typically are errors in the data entry. Payment = $20.00 however entered as 2000.00 etc. Or as has happened twice recently in our clinic - the last 4 digits of the credit card were entered as the payment amount. Resulting in 7000+ and 9000+ entries for a $20.00 payment. It would be great for it to pop up with a question - did you mean to enter this amount ????. Thanks for considering this.
