Amend Form 5500 for Retroactive Fidelity Bond?

[M Gerald]

A client established a 401(k) plan as of January 1, 2020, for which it never obtained a fidelity bond. The plan administrator filed Forms 5500-SF 2020-2022 and 5500s for 2023 and 2024, and correctly check the "No" box for the question of whether during the plan year the plan was covered by a fidelity bond.  The client recently obtained current and retroactive fidelity bonds for all years going back to 2020, and the question is, can, or should, the plan administrator file amended 5500s for plan years 2020-2024 to show that the plan was covered by a fidelity bond?

Thanks for your time!
