Optional Update Form: Should I Mention other College Scholarship Offers?

I’ve been deferred from Stanford as a fall 2016 student, and I am in the process of filling out Stanford’s optional update form. Last week, I also received admission into USC and I was selected as a finalist for the Presidential Scholarship, and I also was invited to apply for UCLA’s Regents Scholarship (only 1.5% of applicants receive the invite I believe). I know that USC and UCLA’s merit scholarship programs are very selective, so I was wondering if putting that down as a new “honor/award” on the optional update form would be appropriate. Stanford is still my number one choice and I really do not want to come off as favoring other schools. If anyone has any advice, it would be much appreciated!
