How to prevent duplicate element/payroll entries when the benefit options are changed

For plans like HSA, the employee contributes one-time lump sum amount to employee upon initial eligibility/enrollment. We need to ensure that this lump sum is paid exactly once per employee, even if they make subsequent changes to their benefit elections (e.g., changing their regular HSA deduction amount, or other plan options). The system should cap the contribution at one time, preventing any duplicate lump sums. I am looking for ideas and best practices on how to implement this effectively in Oracle Fusion HCM, particularly focusing on:

1. Is there any seeded functionality available which serves the purpose.
2. What are the factors to be taken care while configuring.
