Is it possible to lock budget period during year end and record Liquidation as the same time?

Encountered a requirement include both control and reporting purpose.

Control Part:

To prohibit PO created while consuming last year remaining budget through changing budget date.

Solution is to change the budget to close pending

Reporting purpose:

After matched invoice or receipt (depend on whether using accrual at receipt), amount will be liquidated from obligations to expenditure in budgetary control. So that yearly management report can review company expenditure as well as remaining Obligation.

However, once the budget period changed to close or close pending, the invoice and receipt received can no longer pass the fund check due to budget close.
