How to configure HSA plan to consider already contributed amount when annual amount is changed mid y

We want to setup the HSA plan such that when the Annual Amount is changed mid-year, the new value for deduction per pay period is calculated taking into account the already contributed amount till date and the pay periods remaining.

But the system is not taking into account the already contributed amount till date through the payroll runs already taken place in the system.

Example - Pay Periods in the whole year is 26.

Annual Contribution is 2600.

First 3 pay periods payroll has been run and employee has contributed 100 + 100 + 100 = 300 to HSA .

Now employee changes the annual amount to 3750.

System now divides the Annual Amount 3750 by 23 which is the remaining pay periods and starts deducting 3750/23 = 163
