How can we explicitly define Balance Calculation Date for a front loaded annual accrual absence plan

Summary:

How can we explicitly define 'Balance Calculation Date' (as Mar 31 for employees whose holiday plan starts Apr 01) in a front loaded annual accrual absence plan. I can always see 12/31, but ask is, when an employee login and see shall be able to see last calculation date as 03/31 instead of 12/31.
Please suggest a way to achieve this scenario.
