I valued my house on the ACTIVA account 2 years ago. This year the value of the house is less. How can I make this transaction in iCash?

Let me explain how I do it myself. In Assets I created a Revaluation account. To increase my assets value I enter a transaction from a Capital account to that Revaluation account. To decrease my assets value I enter a transaction from the Revaluation account to the Capital account.
