PO rollover process - accounting date for PY in KK

On the PO rollover with PY close encumbrance option, the lines are getting posted (reversed) under original PO accounting date. Is there an option to make the reversal (PY lines) posted to last date of the prior year in KK.

e,g,

Original PO date 06/10/2021 $ 100

AP Actual $70 07/10/2021

Remaining encumbrance $30 at the end of the year 12/31/2021

Run PO rollover process with PY close encumbrance

KK activity table:

06/10/2021 PO encumbrance -$30 (how to make this under 12/31/2021)

01/01/2022 PO encumbrance $30

Thanks!
