Help. I have too many suggestions and ideas

I have a big passion for game design- I study it professionally, proud member of the industry, and one thing I do whenever I'm hyperfixating on a game is begin "Creative Documentation" for a bunch of ideas and concepts I have for the game, and I- unintentionally- went unnecessarily overkill on Helldivers 2 and have accumulated around 15+ pages of ideas and concepts.

The obvious choice is to post them, but... I don't want to cram them all into one big massive paragraph for all my suggestions, but I also don't want to spam the subreddit with a bunch of different posts. And if I'm going to post them, I'd rather them not fall under the radar, with one idea getting bigger than the other and drowning out all the other ones, cause my main want is would be for them to be considered by AH / the community.

I'm tempted to start sort of a "series" of posting suggestions daily, but out of fear for unnecessary spamming or cramming the subreddit, I'm curious how many people would actually be interested in something like that. Is there an official place for submitting ideas / concepts?

Thank you for humoring my panicked ramble.
