There is going to be ability to set depreciation rate and Manager will offer you to create depreciation entries automatically. You won’t have to clone.
Unsure how you are doing this monthly, but until the automatic entry solution appears, it can be this simple:
Create a monthly master journal entry which takes up a close approximation of the depreciation in bulk. Clone that journal entry for each subsequent month until year end month. At year end, do the detailed depreciation per asset and reverse the accumulated journal entries.
