You'll need to wite a VBA Macro to do something like that.
In Rod Gil's book on VBA Programming for MS Project, he has code that will
list all predecessors to a task. As that loops through the predecessors, you
could modify the code to examine Actual Finish for those tasks and then set a
flag for you.
His book can be purchased at msprojectexperts.com
One of the other MVPs also has similar code out here in cyberspace, you may
want to try mousetrax.com
