AMORTIZE ADJUSTMENT

Hi experts

My customer needs the following behavior:

• When the adjustment concerns the life of the asset --> This adjustment must be amortized since the current period
• But when the adjustment for the same asset concerns the cost --> this adjustment mustn’t be amortized.

I know that we cannot uncheck the button of amortize adjustment after he was checked already. What workaround can we use to meet the customer requirement?

please advise.
