Supplement Question

Ok, so i plan on applying to Columbia and one of the highlights of my resume is research I conducted at a university. I wish to send the abstract of the published paper as a supplement but, my intended major is Economics. In my essay I talked about how my many ECs in science lead my to wanting a career in pharmacetical mamangement or something of the sort thus, I want to major in FInancial Economics. But, on the website, they wrote to only send research papers if I was pallning to major in sciences or engineering. Any suggestions?
