Your whole person multiple (WPM)...this is the term USNA uses...can be adjusted for many different situations. In fact, this happens often for qualities/achievements that are not ordinarily found on the application, but are valued by the military/USNA. What you can do is add the additional information into the comments section of your application (typically, the "Candidate Activities Record" portion is the appropriate section) or if you have a resume that complements your application, have a school official sign a cover letter endorsing the resume and then scan/email or mail to USNA. Alternatively, it also might be possible to mention this in a BGO interview. One of the main points of the BGO interview is to fill in the "cracks" of the candidate's application in order to give USNA a full/complete picture of the candidate's background (academic, physical, leadership, etc.).
