Submitting additional recommendations after submission of commapp

<p>Hey peeps, </p>

<p>I submitted my commonapp almost 20 days ago, and I've received the checklist status login for many of the colleges that I applied to. I noticed that in some checklist statuses, there is a space where students can upload additional materials. I would like to submit a recommendation from my sister, as it will provide a new insight into my life. Would submitting the recommendation this way be allowed? </p>

<p>I also have this same question, if anyone could still answer this!</p>
