Adding additional costs to assets after placed in service

Our fixed asset person is out on medical leave and we don't have contact with her. If I recall, if we need to add to an asset already placed in service, via AM20.3, then this will not show up on an asset addition report. Is this correct? Is there a way to rectify this? For rollfward and reconciling purposes and for year-end audit, it is much cleaner if this adjustment/addition shows as a current year addition. Thanks for your help.
