You might consider just using transclusion or macros rather than store
duplicative information.
You can then just use something like {{!!firstname}} {{!!lastname}} or
<<fullname>> where you need to.
You might be able to do what you want to do by hooking action widgets into
a separate button or the system/tiddler save button but it might end up
being an awkward and error-prone way of doing things.
