Proration of Workforce Compensation Plans

Summary

If an employee is eligible for different compensation plans throughout the year is it possible to Pro rate the compensation amounts

We have workforce plans that are eligible for different grades. We have scenarios where an employee will start the year eligible for one compensation plan and finish the year eligible for another due to grade change however the employee will appear on the latter worksheet. can anyone advise if there is a way to automate the proration for both plans or can we only pro-rate the latest plan

Thanks in Advance
