I saw that you can obtain suggested topics from FAQ webpages and works pretty fine!
I'm interested on creating a shared OneNote post with some colleagues where we can add our own questions and answers, so we can give this link to PVA to get this suggested topics and add new ones time to time.
I tried even giving FAQ format, but it seems PVA can't recognize the link.
Glad to hear that you're enjoying the Topic Suggestions feature in PVA.
Your OneNote use case is an interesting one. We currently haven't built in support for OneNote as a source for Topic Suggestions. We'll keep expanding on our Topic Suggestions offering and will share updates when we have more.
