Fixed Assets Valuation Report

Printing this report for a past date, (e.g 31st Dec 2019) does not give the correct accumulated depreciation. Instead the accumulated depreciation will be as of current date.
I realized FA Assets module does not store anywhere Fixed Asset depreciation transactions, instead values are updated into material_cost column in the stock_master table. This makes it difficult to print any backddated report as per any date.

Please advise how to go about this.
