Restricting employees to 2 bank accounts

How do you restrict employees to enroll only 2 active bank accounts at a time with 100% distribution. Infor Cloudsuite GHR allows multiple bank accounts but we want to restrict the employees to only 2 and then force them to specify the percentage distribution to be deposited in each  account  for a total of 100%.

Is there a standard way of doing it or does it require coding changes?
