The pay elements in ePayroll are only able to follow a formula limit per use. You can set a limit for example $200, and the maximum claim would be $200 per time.
ePayroll is unable to calculate and set a limit for accumulative costs annually. In that sense, it also does not have the function to set different max annual limits for different grades.
Our system has designed a module (eBenefit) for employees' claims with many different functions and possible configurations. There you can set annual limits for different claims, and also configure different limits for different grades for staff.
