Pricing: how change pricing date sales order line

Summary:

Based on the company's business needs, it is necessary to be able to change the pricing date of only one line.

I have my price list with the following charges:

Item: 1234
450 USD
Start Date: 09/01/2024
End Date: 09/31/2025

Item: 1234
500 USD
Start Date: 10/01/2025
End Date:
10/31/2026

I need to be able to change the pricing date of a single line so that it reflects the previous price.

How can I solve this need?

I've seen that it's not possible, but is there a way to do it algorithmically using a date from a flexfield on the line?

I don't have redwood
