Applying to law schools while registered for the January lsat

I am currently applying to a few law schools (not early decision) with my scores from the past two lsats. Equally I have enrolled for the Jan lsat in hopes of getting a higher score for some of my less likely picks. My first question is do law schools have the knowledge of you being registered for future lsats at the point of application? If so, do law schools look at applications differently (i.e. more likely to waitlist or defer) candidates registered for future lsats?
