Should I send these updates?

I applied as a financial economics/economics major to Columbia University NYC and UChicago, but I want to add an internship and some other business-related things I hadn’t added in my commonapp because I got these slightly after I turned it in. Here’s what I wanna add:
-leader a major community project called ___ in which I am working with professionals to design a website, database, surveys and other marketing tools to connect donors to the children who are receiving the donations.

  • helped start and received a paid internship at a startup consulting company. I run payrolls and take phone calls. I also do a lot of marketing work for the company, for which I designed the website, flyers, business cards, and edited/designed their guidelines packet.
  • created marketing materials such as flyers etc for other consulting companies
  • invested in stocks and learned a lot about the financial world, which helped me foster greater interest in economics. I constantly keep track of the market’s ups and downs.
  • recently qualified for and will receive the silver President’s award for volunteer service
    I would like to send these updates to them but I don’t know if they’re worthy enough to send. The only thing finance/business related that was on my original commonapp was DECA international finalist and DECA school chapter officer, but I wanna add these too so they know I have more than just DECA. Idk if I should send them to Columbia and uchicago or not. I don’t want them to get annoyed or just think I’m making up fluff.

leader of* sorry there are a few typos here and there. this isnt word for word what I will send but just a gist
