My apologies if this already exists, but I have no been able to find it. I need a tag system (explained below) that can live within the narrative/story but the AI engine (i.e. write/rewrite/muse) will ignore when generating prose. For instance, I write historical fiction, and sometimes, I need to go back and make sweeping edits to the prose to fix references to historical events, settings, etc. To do that, I typically will go to that chapter and put a XX all by itself at the beginning, post notes to me for what revisions need to happen, and a xx a by itself at the end of my comments. Exactly how code does with its comments (i.e. /* type in here what you want engine to ignore */ in TSQL - Yes, I was a DB developer in my previous life).
