Multi period for previous months

Hello Guys,

I would like to know if there is a way to amortize cost for several period at one go in a specific period.

Example of Scenario:

We have received an invoice in Aug-22 for the Amount of $120k which represent cost for Jan-22 to Dec-22 and at time of processing the invoice we will have to expense the cost Jan-22 to Aug-22=$80k and amortize the remaining cost of $40k from Sep-22 to Dec-22.

Actually user is splitting the PO matching line into two

Line 1 = $ 80k - Expense Directly

Line 2 = $ 40k - Multiperiod Accounting Start Date: 01-Sep-22
