Is there a way to incorporate one of your recipes in another?

Example: I make my own seitan. If its calories differ from those of the seitan(s) already in the database and I don't want to add my own recipe to the database, is there any way to take 1 serving of "my" seitan and use it as an ingredient in a chili? (I can put the chili into the tracker minus the seitan and track the seitan separately. I'm wondering if there's another way.)
