Nickname issue on SAT?

So this was pretty dumb in the first place, but I registered for the SAT with my first name as “Will” even though my full first name is William. Yes, it was stupid especially considering I am applying to colleges using “William.” To cut to the chase, should I change my name on my SAT profile to say William so that colleges don’t make a file for Will and then get my William submission and not know it’s me?
Thanks for the help.
Ps. My mom registered me, so it’s not actually my fault.
