Adding fields to existing AdHoc View

Hello,

I'm newer to using the report center but have found a previously created ad-hoc view report that our A&R/Pathways staff likes to utilize for follow up for students who have not completed their applications. When I check the domain, I see that ever available field seems to have already been added into said report. Is there a way to edit domain fields to allow for more data to come through? Fore example, they said it would be useful to know if the student's high school and if they're currently enrolled, is it possible to add this to said report or would it need to be created from scratch?

All help is appreciated. Thank you!
