Is it possible to submit more than one arts supplement (for music and for theater)?

<p>The arts are pretty much my life ... I do a lot of theater, music, and film-making. The Common App arts supplement says "Please indicate your area of interest" and has a place to check the box with your preferred art medium. However, it allows one to check more than one box, so I'm wondering if it's okay to submit materials for a few different mediums? Or should I maybe submit a few arts supplements (if that's even possible)?</p>

<p>I e-mailed the support for the Common App but they misunderstood my question and didn't give me a clear answer....</p>

<p>Thanks SO MUCH for your help.</p>
