Revaluation of Assets from Previous Date

User has forgotten to perform revaluation at previous period and has closed the period. Now user wants to perform revaluation but also requires that an adjustment revaluation amortization entry should be passed in the system for previous periods. Is this possible as i am getting an error of "You must amortize this transaction with an amortization start date that falls in the current period because you have entered a revaluation reserve amount."
