Depreciation rate

Hello,

Please, help - me for the question below.

Tks.

----

As for the months of January / February / March, are entressafra periods (where no harvest and the plant is disassembled for overhaul), in FA for the depreciation of assets to retake it in the month of April when starts harvest.

Therefore, we need the system to amortize those 12 months of the year depreciation in only 9 months. The useful life does not change, you should only change the way monthly falls. 

Is there any form of performing this process by the system? We Need applicable this month, but considering that they are about more than 2500 goods and if the solution is very manual we will need time to make changes.
