How can Revaluation be separated from Current Cost and Accumulated Depreciation

Revaluation is added to Depreciation, Accumulated Depreciation and Current Cost.
I want the system calculates Revaluation but without adding this to the Current Cost and Accumulated Depreciation.

Wrong Accounting because Depreciation Calculation is multiplying Revaluation Factor times Depreciation

The Revaluation must not be part of Current Cost either Accumulated Depreciation.
