Common app question - supplements, editing

<p>Hi,
Although I haven't submitted the actual common app, I submitted two supplements a while back. Before I submitted the first one, I got a message saying something about making multiple versions and editing the app...I (was an idiot) and didn't read the full thing.
Does anyone know what I'm talking about?</p>

<p>I thought it wouldn't apply to me, but now I'm submitting an EA school and I have to submit my common app. But I really want to be able to change it later on...when I submit it for the EA schools will it automatcally send the common app to the supplements I already submitted?</p>

<p>Should I just make a new account and submit my EA school through there? does that work?</p>
