Supplementary Materials?

Hi guys! Quick question that hopefully someone out there will have some insight on: if I would like to attach a short story that has placed in an acclaimed national competition with my application as a creative writing supplement, where would it go? I thought to put it in Additional Information but it’s longer than 650 words, and I’m not sure the Professional Arts Resume upload area is the right place either, since it’s not a resume. Should I include it with the Common App or would there be a place to upload it when we are linked to the portal in February?

Thanks in advance!
