Is there a way to add notes to Trend Journal for tracking Simulation results?

I would like to be able to add a short note to the trend journal after each iteration.  Is there any way to do that?  This way I can keep track of any changes I made to the model without having to have a separate document.  However, if you open up the Trend Journal document and add notes, the notes will be gone when you run the nest iteration.  Is there a handy way to keep notes in a Simulation file as you go?
