CommonApp + Supplement for BU?

Applying to College

<p>For my common app essay, I talked about a important life experience and its impact on me. Thing is that the impact was that it drove me to choose my major. Now Boston University's supplement is asking for another essay to talk about what drove me to choose the field of study that I'm interested. Can I talk about the same event if it is a diffrent essay, or should I try to force a different event that won't come through as clear?</p>
