Take the word limit off the boxes in Story Bible

Every time I want to rewrite or add to the synopsis, outine or character boxes, etc, I have to copy and paste what's in the box into a longer document to rewrite it because the box tells me I have too many words (I delete the unneeded words after I make my changes.) It would be so much easier and faster if I could work/add/rewrite in the boxes in Story Bible without having to do the extra steps of copy & pasting to a different program and then copying & pasting the new version back
