Changes to Housing App

<p>So I changed my housing application for IU after I submitted it (I put Collins as my first choice now and got rid some of LLCs) but I got a call about a certain LLC I had put down as an option but then removed as a preference because it's in Northwest.. I'm worried that the housing people won't be able to see the changes I made after I submitted my application. Should I call them and tell them? </p>
