How do I delete a submitted application off of the common app?

Applying to College Common and Coalition Application

So I wasn’t accepted into a main school, but my admissions letter told me to apply for a branch school. The problem is, is that the school only takes applications through the common app. I do I delete the submitted application to reapply to a branch school?

From the CommonApp website:

Which university is it? Maybe you could email them asking about this.
