Is 'Plan to Enroll' required by 4/30?

Hi all, for the 'Choose Your Medical School' tool I was wondering if we have to select 'Plan to Enroll' by 4/30. I am on a WL for my dream school and unsure if selecting something would affect my chances at my dream school. Feeling super fortunate to be in this position but also wondering if 1. I have to plan to enroll and 2. if it would affect my WL chances.
