Brainstorming ban list

I loved the brainstorming tool, but even when I would give an idea a thumbs down, it would bring me 10 variations of that idea. I was specifically looking for ways for two characters to meet in a romance, and I said no to cafe, and no to park, and no to therapist's office, but it kept coming at me with those settings; it made me wish there was a way to update the brainstormer with banned concepts so that it would actually stop producing parks and cafes and therapists when I was sure I didn't want them.
