Capturing Edit Events for Non-Versioned Items

Is it possible to capture the edit/done event of an item that is not versioned?

For example, for itemType Manufacturer, which is set to not versioned, I want to capture the event when the Manufacturer name changes, preferably when Done is clicked.  I've looked at the OnBeforeAdd, OnAdd and OnAfterAdd events in the item types ClientEvents tab but none of those events appear to fire for changes.  I did look at adding an onChange event to the name field in the Manufacturer form but onChange can capture too many events before the Done is clicked.
