One way to do this is to provide information that qualifies and quantifies the awards. If you received award X how many others were eligible for the award and how many awards were given? Were you the first recipient ever out of 32,000 potential award winners in 11 years to earn it or were you 1 of 10 people that got the award out of your class of 30. You should also do your best to articulate what the award was given for as well. If 10 people got the award for having a 4.5 GPA and you were one of them that is not too shabby. There should be away to submit a "resume" - I would provide as much detail as possible.
You should also take the opportunity to describe any slight mods you make to your radio button extracurricular list. For instance - if you were a team captain at your school for judo and judo is not listed - I would select team captain for wrestling and then make it clear on your "resume" that it was judo. The more you can inform the panel "scoring" your package the better. However, do not over embellish. I also agree that demonstrating leadership is critical.
