Well ive been looking around with little luck. The forum in question is actually bbpress already. I posted that question in both bbpress and buddypress threads.
I have a plugin like this that works in phpbb but there doesnt seem to be anything for wordpress yet, if I knew more about writing code id just write it myself.
While looking around I saw this dev who seemed to be working on something like it using ACF, but it doesnt seem to be live

Associate a Form with BBPress Forums – So you can create a Support Request form that Users are required to complete before submitting a Post in any categories you specify
Ive been hunting around the page here and saw this page

I just dont know how I would make it post into bbpress instead of making a new wordpress page
