Foreign Bank Account Revaluation Wizard

The tutorials and help articles for this topic all state that once a foreign bank account is revalued with a new FX rate - any transactions PRIOR to the revaluation date will also be effected.  Does anyone know how FAR back this revaluation will go?  I'm assuming, say for example i'm in financial year 2022 on Sage, if my revaluation date is 31/5/22 for example, it will revaluate any transactions posted to that bank account from 1/1/22 to 31/5/22?

Thanks
