So if I'm understanding correctly, you want to drop some fraction of a project, but keep some notes on why you did so? Perhaps there are three ways to accomplish something, and you've decided that two of them are not workable, and you want to document that while clearing the decks to do the third?

What I do in that sort of situation is to simply add a note to the action explaining what I did or didn't do, then mark it completed. You could preface the action name with "Dropped:" or "Did not do:" or whatever to make it easier to search for such actions.
