Thanks for sharing this idea Tommy- we'll leave this open for voting as I know it's something that has come up in conversations with clients, but I don't see it on the Community right now.
We do have some clients using work arounds to meet that same need.
Using "Questions" that are required has worked well for some.
Other clients include a message on the same web page as their MySchoolBuilding link, noting that setup description is required. They also include this message in their special space requirements/policy documents. If the requester does not add their configurations in the setup requirement field (Event Setup), the request is declined and must be resubmitted.
