[Zope] More verbose undo/transaction desciptions

Is it possible to make the Undo tab's list of transactions more verbose? Say that I change the value of one property of an object, and then at a later time change another property of the same object. In the object's Undo tab, there's only displayed, that I called the "editTheObject-something" method twice, not which properties that were changed. Is it something that I tweak in my product's code? - Carsten
