I wanna confirm the formula of Create Multiperiod Account amount calculation and change it

When we run the create multiperiod accounting process, it will calculate the amount for each amorized month. We set the start date and end date duration as 1 year in the test, but the multiperiod amorized into 13 periods. Whether there is any configurations that we can change to only actual duration month amorization?

Test Examples:

For invoice#TEST080501, we wanna the amorization can be Jul-2024 as 1 month and 7 days. and Jun-2025 as 23 days. Other month keep as whole month allocation. How can we do this?
